I think it's a bit much to criticize being contrarian, when being a conformist is basically the same thing.

A conformist does exactly what the public does, and a contrarian does exactly what the public doesn't do.

Either way the public decides.

If you independently decide that you don't like social media, then that's not being a contrarian. Just as independently deciding that you do want to engage in social media doesn't make you a conformist.
