I mean, seriously, if whatever they posted on Twitter actually helped anyone (I'd be surprised, but what do I know), then obviously they'd want to deliver it through every channel available to as many people as they can. If not, and they just want to show their protest by quitting — well, at least they could have tried to get themselves banned on Twitter and whine about it later everywhere else. But this — it's just pathetic.

Kalshi and PolyMarket are doing something absolutely wonderful for those people (i.e. the only people who should care about these "prediction markets" at all): they actually make betting fair, which was impossible before. It is not impossible now, because in fact there are much better decentralized markets than these (basically all you need to make a completely decentralized betting platform are Ethereum contracts), but they are handier to use and hence more popular. But it was impossible with traditional gambling, where a bookmaker can set any odds and reject any bets.

Now, honestly, I have no idea why would one spend resources on uploading terabytes of LLM garbage to arXiv, but they sure can. Even if some crazy person is publishing like 2 nonsense papers daily, it is no harm and, if anything, valid data for psychology research. But if somebody actually floods it with non-human-generated content, well, I suppose it isn't even that expensive to make ArXiv totally unusable (and perhaps even unfeasible to host). So there has to be some filtering. But only to prevent the abuse.

Otherwise, I indeed think that proper ranking, linking and user-driven moderation (again, not to prevent anybody from posting anything, but to label papers as more interesting for the specific community) is the only right way to go.

And, FWIW, I do think that arXiv truly has a vast potential to be improved. It is currently in the position to change the whole process of how the research results are shared, yet it is still, as others have said, only a PDF hosting. And since the universities couldn't break out of the whole Elsevier & co. scam despite the internet existing for the 30 years, to me, breaking free from the university affiliation sounds like a good thing.

But, of course, I am talking only about the possibilities being out there. I know nothing about the people in charge of the whole endeavor, and ultimately in depends on them only, if it sails or sinks.

And framing it as "sell-outs" is cheap rhetoric that means nothing. The fact is, they were the company who never really had a solid business model, but provide a lot of value for the community. Being acquired by some infinite-money company was always the best outcome they could hope for. Well, they did. Probably got a ton of money. Will it require some sacrifice? Well, some people would say that working for a company who makes products for the Department of War of the USA on conditions that even Anthropic found too ugly to satisfy, is enough of a sacrifice on its own. I am pretty sure though that most people would be willing to make this sacrifice for the right amount of money (with "right amount" being a variable part). So calling someone a sell-out is usually just bitterness about the fact that it wasn't you who managed to sell out. I mean, not judging someone for a sacrifice they make isn't the same thing as pretending they didn't make a sacrifice. Sometimes we (the world, they were trying to make better) are a sacrifice. That's all.
