Maybe, but even if that is the case it's sooooo much better that even the worst case (fork when they try to monetise it) is way better than any alternatives.
To maintain a successful fork, not only are you going to need to find people who volunteer for maintaining a fork at that scale (including a large user base due to popularity), you’ll need to find skilled Rust developers, too.

That’s going to be immensely difficult.
