setting aside the understanding of hypocrisy as entirely negative, deadnaming is bad because it can allow for unwanted tracking/attention, and because it might be offensive/hurtful for the person you are calling a name that they do not use.
neither of those issues apply for companies. unless you've relentlessly refrained from calling McDonald's "mickey D's" (or any other company, any name other than their company name) specifically because you "might offend them" (they have a "preferred" name, that's why they put it everywhere), then you're not applying the rule universally. and if you worry that using "twitter" in place of "x" would somehow allow for stalking of the company that the real name would prevent, I would love to see any rational justification for that concern.
rules - of morality or otherwise - are reasonable to follow only when they have some net benefit. even by the low standards of an edgelord trying to apply rules where they would be ironic, this fails the test of even applying the rules correctly.
