I can see things going very sour if they choose to replace long standing mods.
As opposed to the current state of affairs, where it is someone you didn't pick, also with zero vetting.
The current set of volunteer mods are by far Reddit's largest asset - especially on the major subs.
That means they'll let these subs go dark, claim they're unmoderated (even though they could take over them right now), and expand their internal moderation team.

Just because you don't appreciate the work that other human beings do doesn't mean that they deserve to be treated like shit, nor does it mean that when they stand up against greedy bastards who care neither about them, you, nor the product or service they're selling you should throw them to the wolves just because it inconveniences your life.
The answer overwhelmingly is mods and content creators, the most important people to Reddit's success.
