Unfortunately Meta has proven itself to be untrustworthy. Over their entire lifespan they’ve shown through their actions, and their statements by the CEO time and time again, that their main objective is to make the most money possible by exploiting their user base by any means available.
They’ve long ago lost the credibility to be given the benefit of the doubt. They’re terrible, they know it, and they like it that way.
