Ever since the shutdown of the side-load they've been pretty vocally anti-anthropic on twitter. Paranoid that anthropic is going to torpedo them via some backdoor now that they own bun, insinuating that anthropic shut down the auth from a position of weakness since OpenCode is a superior product, etc.
The thing is OpenCode IS a great product, I'm not sure it's "superior", but unfortunately the way things are evolving where the model + harness pairing is so important, it does seem like they are in a similar position to Cursor (and do not have the resources to try to pivot into developing their own foundational model).
I wouldn't call OpenCode a "great" product tbh. It's nice that it's FLOSS of course, but the overall quality is a bit underwhelming and it's clearly possible to build much better open agentic harnesses. It would be nice if more people tried to do this.
I think frankly OpenCode is delusional to think that Anthropic is actually "concerned" with them in any way. Anthropic's concerns at this point are on the geopolitical level. I doubt stamping out ToS-violating usage of their subscription services is even on executive radar. OpenAI only allows it because it's a cheap PR win and they take those where they can get them.
Yeah, I recognized the PR author from Twitter (same avatar) and man he really does come across as incredibly juvenile. Shamelessly talking up OpenAI while shitting on Claude models and the motivation is just so transparent.
Valid question. It's because they have a separate product intended for use with general tools: Their API.
Their subscription plans aren't actually "Claude Code Plans". They're subscription plans for their tool suite, which includes claude code. It's offered at a discount because they know the usage of this customer base.
OpenCode used a private API to imitate Claude Code and connect as if it was an Anthropic product, bypassing the need to pay for the API that was for this purpose.
Anthropic has been consistent on this from the start. The subscription plans were never for general use with other tools. They looked the other way for a while but OpenCode was openly flaunting it, so they started doing detection and blocking.
OpenCode and maintainers have gone on the offense on Twitter with some rather juvenile behavior and now they're trying to cheekily allow a plugin system so they can claim they're not supporting it while very obviously putting work into supporting it.
Most of the anger in this thread comes from people who want their monthly subscription to be usable as a cheaper version of the public API, even though it was never sold as that.
This has been explained many times in this thread. Your subscription to Claude models for use in Claude Code is subsidized. That is, it is only meant to be used with that harness.
When you use that API key with OpenCode, you're circumventing that.
The PS5 is subsidized because the make money with the games.
Printers are subsidized because the make money with the ink.
The API use is subsidized because they make money with Claude Code?
I would understand if Claude Code could only be used with Anthropics API but not the other way around. 1 million tokens is 1 million tokens unless Claude Code is burning tokens and others are more efficient in token use.
I'd say that they want Claude Code to become the standard, so that they can milk corporations on enterprise plans. We individual subscribers are nothing, but we'll go to work and be vocal about specifically having Claude.
Because models are quickly moving toward commoditization, whether the big three like it or not. The differentiator now is tooling around those models. By eliminating OpenCode's auth stuff, they prevent leaking customers onto another platform that allows model choice (they will likely lose paying customers to one of the major inference catalogs like OpenRouter once they move from Claude Code to OpenCode).
Why does Netflix care how the movies they stream to you are consumed? Shouldn't your $8/mo allow you to stream any movie to OpenFlix and consume however you like?
You are also not allowed to show these Netflix movies on a big screen in front of your house and charge people. The 8 dollar are for a specific use case, just like the tokens in the subscription.
If you use Claude through an interface that’s not Claude Code, you’ll only stick with it for as long as it proves itself the best. With other interfaces, you can experiment with multiple models and switch from one to another for different tasks or different periods of time.
Those tokens going to other providers are tokens not going to Anthropic, so they want to lock you in with Claude Code. And it clearly works, since a lot of people swear by it.
because he is giving them at 90% discount in their subscription.
they are more than happy if you use the tokens at api pricing, but when subsidized they want you to use their claude code surface.
On what basis are you assuming that Anthropic committed greater copyright theft than Meta, OpenAI, and Google (not to mention many lesser-known options)?
Source: i run pretty much all of these agents (codex, cc, droid, opencode, amp, etc) side-by-side in agentastic.dev and opencode had basically 0 win-rate over other agents.
Anthropic provides subsidized access to Claude models through Claude Code. It is well understood to be 'a loss leader' so that they can incentivize people to use Claude Code.
OpenCode lets people take the Claude-Code-only-API-Key, and lets them use it in a different harness. Anthropic's preferred way for such interaction is getting a different, Claude API key (and not Claude Code SDK API key).

A rough analogy might be something like getting subsidized drinks from a cafe, provided you sit there a eat food. What if someone says, go to the cafe and get free drink and come sit over at our cafe and order food. It is a loose analogy, but you get the idea.
If it wasn't the case, the Claude API pricing would be the same, $200 for unlimited use. But it's metered.
We don't know if Claude Code bleeds money for every user that touches it. Probably not. But the different pricing is a strong enough clue that it's an appeal product with subsidized tokens consumption.
API is intended for a different audience - companies with a big pocket who aren't as price sensitive as private users. So the pricing will be different than for a private subscription.
There is huge value in getting people to subscribe to recurring payments. Giving people a discount to do so makes sense and does not mean that the subscription service loses money.
