Defining “better” isn’t easy, but “more valuable” is a falsifiable measure. I hate Facebook and Google but they do provide a lot of value to their customers (advertisers)

Facebook's effect on society is still being studied, the jury is still out. It may very well be more damaging than doing good. Just because people are paying for something doesn't mean its doing anything good. Tobacco is a good example.

Like it or not, there is also a huge amount of legitimate interactions on facebook.

My dad didn't use internet forums before.. now he's on facebook groups about wood working -- I doubt the projects and reviews people in those groups share are fake news :)

Fact is: without facebook my dad probably wouldn't participate in any online community.

Right, thats why uber recently discovered that massive fraud in ad spending did not affect their sales

Hehehe, on average maybe? That said you probably shouldn't live your life by statistics.

Also note: I did advice against going all Ferengi :)
