Who's to say there's no incentive. Anthropic using Bun internally is plenty incentive to make it better even if for their own use-case. I think it is a bit of a doomer perspective to think anything being bought out means the end of the line for that project. Sure, some things might change depending on the interests of the new owners but that's not to say it'll automatically become bad. Microsoft bought Github and Mojang, they're both doing better than ever for example

GitHub is without question worse for users now.
