Probably because mods are unpaid and not employees.
Not because of the overall community, but because of business actions, manufactured turmoil, and well funded trolling.
Proof? Read about how reddit suppressed dissent during the pandemic.
I'm not going to post any particular link because the topic is too political and every source (left and right) spins things in some way that I dislike.
The facts, without spin, are these: reddit banned and/or quarantined many anti-lockdown subs. Initially, they said they would not, because "Dissent is a part of Reddit and the foundation of democracy", but ultimately, they did.
You should cite sources instead of saying the equivalent of "do your own research "
