Are right wingers creating FUD around Signal? - Leminal Space

So this is the sort of claim where sources would be really nice. I don’t like Musk, but I’m not about to blindly believe everything said about him.

Remember how CrossFit got popular and then everyone hated it and the only thing more annoying than a vocal crossfitter was a vocal opponent of CrossFit who knew nothing and had merely jumped on the hype train?

Musk is CrossFit, right now. A powerful, dangerous CrossFit. Don’t undercut criticism of him by making lazy, unsubstantiated claims.

Musk himself hasn’t actually provided any sources either, all his statements made on Twitter recently are basically pulled from thin air, almost like vague references
I’m sure it has nothing to do with musk planning his own encrypted Twitter DM feature.
That already exists, but it’s weak in terms of encryption.
