I get what you're saying, having just nuked my nearly 12 year old Reddit account yesterday. Things changed a lot, and I'd definitely say most of it was for the worse.

However, I don't know if this, for lack of a better term, superiority complex, is particularly helpful The fact is that early adopters and enthusiasts made Reddit a cool and useful platform, and so more and more normal began using it. The only way to prevent that from happening is to make a platform actively unappealing, and I wouldn't say that's exactly a good idea. The best thing, IMO, is to stay isolated from monetization incentives and ensure that communities of like-minded people can be formed and interact with each other in a healthy way, both normie and enthusiast.

I mean, if Reddit today magically became a non-profit, reduced the API fees to cover only costs, and eliminated active monetization schemes, that wouldn't suddenly revert the user base back to the way it was a decade ago. The presence of the "ignorant unthinking majority of the lowest common denominator who believe everything they're told" is not dependent on the pursuit of profit.
