I could see cryptobros and the “investing” subs spending a lot on this. They were already buying tons of awards to hype themselves up.
Any unironic circlejerk cult will by buying these and pinning them on each other’s chest, same as the dumbass awards.
I think reddit knows their target audience pretty well; Rubes. That’s why they let all the toxic “stock”, crypto-scam and political extremist subs stay open until the media starts writing stories about them. Gullible idiots spend a lot of money trying to make their opinions look smart and popular.
This will make Reddit a lot of money in the short-term, but probably push more legitimate/casual users away as these “premium upvotes” will surely effect the algorithm and push more nonsense into people’s feeds.
Now that i think about it, this will probably help advertisers and political groups astroturf all of reddit.

It’s hard to not sound snarky here, but you could play another system that’s not seen as a commodity to be passed around Corps for profit.
I switched a couple years back, and honestly couldn’t see going back even before their licensing drama. As a GM, their books are so hard to make work, and expensive for what you get. D&D became too much of a product, and the game has suffered. 3rd party stuff has always had better value and usability compared to WotC books (few exceptions), and other systems give much better support for GM’s to actually run the game.
The coolest shit you do in D&D is the stuff you’re group comes up with at the table, and you get that with any system. Tencent also can’t buy that, so there’s nothing stopping you just playing 5th Edition, and not 6th (or One, whatever Marketing ends up calling it).
