Convenience, short sightedness, and outright lies. Most won't directly be affected by Reddit's recent changes, so it's more convenient for them to just not care and continue using the site uninterrupted. For now, those money-hungry policies don't affect them much, so they'll just not care about it, until of course the ever growing hunger of capital requires more money, thus leading to more restrictive monetisation schemes (Twitter is considering limiting DMs without a subscription now, for example). And of course, you have people buying into the lies that that is the only way for sites like Reddit to exist, nevermind any alternatives (both to Reddit itself and within its monetisation plans).

From what I've seen many of them seem to hate the fact that moderators have banned them, so they're happy the mods may be removed from power.

Most of these users are right-wing, and seem to forget that any mod removals will be replaced with another mod and transphobia, homophobia and racism are still against reddit's code of conduct.
