A lot of Mods might be looking at all the work they have put into their communities over the years and think "I can't leave all of this." Which at this point, given Reddit Corp's behavior, is a sunk cost fallacy.

It's time to jump ship, or learn to live with the new reality. Which is really the same as the old reality, the thin veneer of civility has just been stripped away. This is Capitalism and it always turns out this way. Just look at how many products have been ruined, because someone, somewhere decided they needed more money. Anyone familiar with Hasbro's heavy handedness with Magic the Gathering and Dungeons and Dragons knows what I am talking about.
