> But then tell me how would you run a platform that costs hundred of millions dollars without ads and without fee? Is that also too hard to comprehend?
No it isn't hard to comprehend but it isn't relevant here. Privacy doesn't mean no ads and nobody is preventing facebook to require users to pay a fee.
It is similar to organs. It is illegal to sell/buy them. You can still freely give them away(donate them). Privacy is similar to that. You can't buy/sell it but you can freely give it away. In this situation Facebook seems to be trying to sell you your privacy.
