It looks like he wants to turn twitter in to twitter with kijiji. Not really sure what part of this is a social network. He wants a marketplace that he can get some money back.

I think it is very bold of him to claim starting from zero would be slower. He has accrued so much hate that if he were to start one I can't see how it would turn out any different than truthsocial or if Biden started his own social media platform.

Although I do think it's doable if he somehow kept the fact that he is at the helm a trade secret as he gradually grew the userbase until reaching a certain critical mass and finally revealing that he's the owner.

I think the hate is mostly from media turning against him, which IIRC started to happen before the Twitter debacle. What has he done that normal people would care about enough to start hating him?

I would still expect some hate from the sort of people who (rightly) complain about Google Reader being turned down. But normal people don’t care about that sort of thing.
