That's reversing the argument. I'm not saying quitting X is bad for X, I'm saying quitting X is good for you. Nobody's completely immune to whatever that sociological experiment is turning into and staying on X is likely to influence your ethics, morals and standards in an objectively negative way.

Even personally, you couldn't possibly know whether it's positive or negative for a random stranger on the Internet, because it depends on how much they use it and what they use it for.

For example, keeping a Twitter account in case someone wants to contact you seems pretty harmless.

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.
