Yeah, no. there are many worse news than this.

In the worst case, Astral will stop developing their tools, someone else will pick them up and will continue polishing them. In the best case, they will just continue as they did until now, and nothing will really change on that front.

Astral is doing good work, but their greatest benefit for the ecosystem so far was showing what's possible and how it's down. Now everyone can take up the quest from here and continue. So any possible harm from here out will be not that deep, at worst we will be missing out on many more cool things they could have built.
