The best way to predict Fuchsia’s future is to look at its hardware architecture support and which runtime is getting attention.
Having tea leaves instead of a public strategy and roadmap is what's causing the FUD in the first place. Google probably has good reasons for not making any promises but that hedging comes with a cost.
Feels like a quirk that some of its originators are open source hackers that ended up with Fuchsia being published externally at all. Google definitely doesn't want to attract more killedbygoogle headlines for its experimental projects, and I haven't seen any public Fuchsia evangelization.
If your target platforms are your own smart displays and maybe replacing the Linux kernel in a stack that already doesn't use the Linux userspace, why would you want to spend effort supporting third parties while you're still working on fundamentals?
