That's the beauty of the open source, self-hosted option then, no? If they radically change pricing one day, pick up your ball and self-host without any limits.
No because they add limits to the self-hosted versions too. self-hosted Mattermost or Gitlab instances don’t have access to all the features. Prefect even removed basic features from the self-hosted version (webhooks) to force people to use their Cloud offering.
And that's exactly why they don't do radical changes, because people hate those. They do slow, small and insidious changes over a long time period. And then it isn't as easy to simply "pick up your ball" and be on your way.
