Well that's certainly disappointing but not really a rug pull so much as just what eventually happens with every project, which is that at some point the original authors stop contributing to the original vision. Both of the mentioned projects also don't use BSL, which I feel it is worth reiterating is still a very permissive license. If you aren't planning on selling licenses to the project you are contributing to, then a BSL isn't going to meaningfully restrict you. Sure, fewer contributions is a theoretical concern, but fully permissive licenses also suffer from contributions not looping back into the original project. Or if you use something in the GPL family there are other implications. I've been reading a lot about licensing lately and there don't seem to be any obvious choices for authors who care about how their work is used. I'm gravitating towards BSL though because it is relatively simple and feels like it retains the most important aspects of open source, which are redistribution and modification.
