maybe the REAL problem
maybe the REAL problem is less in the hands of Facebook, but rather the fact that zillions of people are WILLING to BE EXPLOITED by them...
and as you can't go around protecting people from themselves in a FREE society, you end up with "that kind" of solution, i.e. gummint regulators increasing their own power at the expense of freedom.
perhaps there's a simpler solution: hold FB accountable to existing rules, and make sure they're enforced. And clarifying the use of tracking and other information, via "opt in", with GDPR's 'right to be forgotten', should be enough. So yeah, just a few tweeks to what's there right now oughta do it.
But yeah politicians LOVE to pontificate, don't they?
"for the children - for their own good. because we're good people and we know better..."
