Yes, all of this happens (and worse!) and still no boycott of Facebook. We have been turned into a country of dopamine deficient addicts.
And now these same companies are funding a useless war, killing innocent children, and soon, collapsing the world economy.
If you still use these platforms knowing what we know now you are just as complicit as every executive.
On the other side of every "useless war" is the what if question. Killing Hitler before WWII would have been seen as a cruel interference with German sovereignty.
Anyway it would be wise not to tie social network corporate affairs to the war. The two are not linked in a more significant way than a social network in general being linked to such affairs as a media.
Facebook is an addiction for many people. Mark Zuckerberg thinks Facebook users are "dumb fucks":

I haven't logged onto Facebook in some 6 years now, so I can't really do much more to boycott them.
That's the big issue of the post truth era. I imagine the number of people "using these platforms despite what we know" is minuscule. Most will never hear of this, and many who do know have probably left long before this for the other dozens of crimes against humanity Meta's performed.
Of the rest of this list. Youtube Premium is the only thing I'm still subscribed too. I actively unsubbed from Prime and am setting up to unsub from Google One.
Hard to boycott something you quit using 10 years ago.
