Whether it’s a rage-click community, a community made for an agenda, or both, I don’t know, but in either cases, I wouldn’t see as surprising for the mods in such a community to be very trigger-happy. Best you can do, I think, is to block communities and individuals with such a profile, and to recommend others to not engaging (remember to explain why if you do it, btw).
I can conjecture some things, though I can’t be 100% sure on either:
First, maybe it’s fanatics/fanboys that don’t like competition making their platform less relevant. Second, it’s paid actors complaining. Third, it’s robot accounts making posts. Fourth, as proposed in the OP, people are getting the wrong impression due to noisy and problematic bubbles. Fifth, people being scared of leaving their comfort zone. Sixth, a mix of either some or all the previous possibilities.
