No, you shouldn't be using Twitter/X. You shouldn't do anything that validates Elon Musk.
But the power users are addicted and there's nothing comparable to move to. Mastadon didn't pan out and Threads is just...there, and doesn't really foster the political/social commentary circlejerk like Twitter did.
So they will continue to bemoan Elon for moral and ethical reasons and cry about the enshittificaton of the platform but never stop using it.
