I'm increasingly convinced that these kind of leaks are the only effective resistance to this surveillance society we're entering. Meta will keep doing this, and other employers will probably follow, and then of course governments will use "appropriate legal processes" to add the data to their dossiers, etc. We are watching in real time the expansion of surveillance cameras, chat control, deanonymization, etc.
Leaks of this data make it obvious to everyone how much a liability it is. Meta Execs have their data in this pile as well; soldiers and congresspeople are in Flock's database. How many senators do you think PornHub has an accurate taste profile for?
Of course there's harm that comes with leaking this data. But is the harm really greater than everyone being surveilled by everyone, everywhere?
