Apparently the user himself claims to be elon musk, but the most convincing thing so far is that there was some sort of a thread where he discussed the idea to make non-logged users unable to see the content, and hours later this change actually happened on twitter.

The only thing I can say is that if it’s actually him, we will just once again get a confirmation that he’s cringe, for now, whoever this is, is incredibly cringe, even if it’s not elon musk.
