Regardless, I don’t see how they could dictate anything since they lack power over the devs.
Lacking power doesn't mean that no attempts are made. You can be as polite as you want if I don't want to build that observation post and you keep pestering me that's an attempt to dictate what I do with my time. Even just dealing with the pestering is a time sink.
You keep characterizing them in negative ways, what’s that about? I feel like I’m missing something here
I've dealt with entitled users before. The wider FLOSS community has oodles of experiences with toxic behaviour from users, nothing about this is new or even surprising if you've been in the space for a while, it's all the same pattern: First they act like they're paying customers, then you tell them that they're not (but that patches are welcome), then they say "well I'll never use your software if your attitude is like that", then you say "fine with me", then they either leave or start to shout, at which point you block them. A FLOSS project needs healthy erm ego boundaries or it dies because nothing ever gets done.
FLOSS developers contribute because they want to build a specific thing. Conversely, if you want a specific thing that noone else already built or is excited to build, you have to contribute. There's no such thing as a free lunch.
