Well, sure, if you're exceptionally picky about non-normative use cases you can probably find a use for it that is not harmful to the average person. But you're doing a lot of heavy lifting already to justify a positive use case (contacting a person you apparently have no other way of reaching, which isn't in the top 3 of primary use cases for X). Anyway, I was speaking in the aggregate. X (so, post Elon) has been bad for society as a whole and if that's not an objective statement then it is at least close enough to make no difference. I suspect any arguments to use it anyway probably boil down "but...I like it". And since we live in a free world that's a good enough argument to have. It is not, however, harmless.
