The people who want opt-in are not the bad guys here, and neither are the people who want opt-out. The bad guys are those who poisoned the well, tragedy of the commons, by abusing the system. Unfortunately, there is a greater chance of abuse than there is utility, and it's more difficult for everyone to manage opt-out on an individual occurrence basis than it is to manage opt-in centrally by trying to ban bots across the board. And neither are that actually that successful, despite there having been individual successes in some communities.
