> A for-profit company that has dedicated full-time employees that have full support and own the direction of the open source project (go, swift, java)

I think this has not been the case for Java in quite a while. It is a community project now.

It’s really hard to come up with better conditions for an open-source project than what libghostty has. I’m pretty sure it will be the last terminal emulator at this point.

you missed the 99% case, which is some random person who has a reasonably well paying day job and develops the project in their spare time. AI agents make that more sustainable, not less. vim is a good example, as are a lot of popular programming languages.
