Almost every app wants to be a wechat esque app. Musk mentions all kinds of goals about twitter all the time, and none of that info can be used to understand his real goal. The economics of that business is irrelevant (yes, it is lucrative and everyone wants it). You don't become wechat esque by charging people money. And if that is the goal, you should be hiring more and more to add features, since that's what a super app is. Nothing Musk has done aligns with building a super app.

The reality is that he vastly overpaid for twitter, and has no way of making good money. Hence all the antics. Had he bought it at 10B or so he would have a better chance of making money out of it.
