At the end of the day, they are volunteers who are now boarding themselves behind the property of their digital landlord so the risk of eviction isn't really all that surprising.
I've seen endless complaints from users who feel personally offended by being muted/banned from a community and a common response to their complaints is "if you don't like it, go to another site". If the moderators are not happy with the direction of the platform, they are free to vacate the property willingly or have an admin spend :30s removing them.
The relationship has always been unilateral in favor of the people who actually work there.
