So let's get this straight. You admitted you make money off ad revenue which is 100% a business of using a platform for one thing (the thing people want) to instead allow random people with money to force information on other people to get them to think and do things (when said target people would, almost by definition, prefer not to think or do those things), selling people's attention and interrupting their lives on the regular, subtly coercing them using whatever deceptive tactics work best (the kinds of psychological and neurological vulnerabilities that exploit unconscious mammalian behavior), and seem to think that nothing in the social contract constrains you from vetting what garbage lies people put in the ecosystem, as long as you are making money.
Hard disagree on that being "moral". You let people put ideas into other people's heads because they pay you. And we're not talking "good" ideas like education and facts, but usually vapid consumerism crap at best and viral lies and propaganda at worst.
