Ultimately every FOSS project like this that I've run into is (or becomes) selfish in this way.
This is hard to describe. It's like... in FOSS we are meant to all have equal power. But devs sometimes think that means we should all have equal skill, and if they can fork the project so can I. And if I can't, it's just because I haven't learnt how to code then that's just a formality and a matter of time and work, and I can go and do that.
(I can't.)
