A few months before I completely left Facebook all I saw on my feed were ads. Absolutely no content from friends. The only way to see that they had updated anything was to go to their page. I would follow them and still no updates on my feed at all.
Facebook is not a social network, now it is only an ad network and the ads were rarely relevant. It’s not even good a being shitty.
You asked for evidence.
Then you disputed the evidence presented.
Then you admit that there was evidence but not enough to prosecute. That was the same evidence you just disputed.
Seems like you won’t be satisfied with anything other than your preconceived beliefs.
