That’s a very old post but yeah, it is, so is Ghidra (a retro-engineering tool). A lot of people have had the exact same argument of “the NSA made it, it has to be evil!” but lots of security people dissected the code (the fact that it was made by the NSA probably made more people look through it in fact) and no backdoor has ever been found in years. It’s safe to use.
But think about it though, it could be a way for X users that are prone to identity theft to be easily recognizable, like for instance if you’re notable enough they could verify your ID and then give something to your profile so people know it’s the real you! I’m thinking maybe a Blue X ?
You all can’t see Musk’s genius, that’s all.
