Do we know who is funding this? is this one of these things where Meta doesn't want the responsibility for this, so they are pushing to have the OS have the responsibility or something like that?
Facebook. There's a wave of child endangerment lawsuits incoming and they want to head that off at the pass by having governments shift all that liability over to the OS vendors.
Apple, Google, Meta and Microsoft. Maybe with a push from 3 letter agencies, because it makes their life easier.
It is literally just Meta. https://www.gadgetreview.com/reddit-user-uncovers-who-is-beh... https://old.reddit.com/r/linux/comments/1rshc1f/i_traced_2_b... https://tboteproject.com/
