Saying distrust is an ad hominem is one of the takes ever, lol. And that's what all of this boils down to, trust. Do we trust Meta with not exploiting all of our data, and turning it against us at the earliest opportunity? Do we trust Meta that they want to contribute to the fediverse, and not just hurt it because it's a competitor?
By the same logic, blocking or banning a person instead of vetting every post and comment of theirs would also be an ad hominem. But at the end of the day, it's just practical. Meta has a long and not so proud history of being extremely anti-consumer, and shoving that track record under the rug, trying to absolve them of responsibility and consequences for their actions, under the thought-terminating cliche of an ad hominem is neither productive nor practical.
Yes, people are mad at Meta, and yes, the distrust means their actions are scrutinized more than they otherwise would be, but that doesn't mean that their actions aren't actually massively anti-consumer, and that they aren't a massive liability. In this particular case, you can make the argument that they had a legal obligation to hand over the data, had they not tried to build a walled garden with no privacy they wouldn't have had the data to hand over to begin with.
