There have been many examples of executives and engineers who have spoken to this effect:

Good point, but I'll add: if the ideas they are spreading weren't infectious, they wouldn't be spreading them in the first place.
I've been on FB lately because my local government has decided that it will use FB to give background info and outlooks wrt Covid-19. From what I saw in the local groups, the "ideas" people spread are not original content, ever. They don't have those ideas, they just read them and say "yeah, share", so the ideas that make it to your feed have proven themselves many times to be infectious. There's a reason we call it "going viral".
We are simply living in the Eternal September.
some time ago I would have agreed on some level but there is too much manual and/or algorithmic manipulation to encourage "retention", "stickiness", "addictiveness" (whatever the current marketing-speak du jour for dependence is) to be a true reflection of behavior.
thats the irony of the current state of social networks - its not just merely allowing conversation/connection; its about encouraging rage, confrontation, polarity. in the pursuit of metrics, ergo dollars.
and even worse, we then look at the distorted reflection we see in the digital mirror and our view of society/discourse is negatively reinforced. what a loop.
As long as:
1) people want to socialize freely (as well as privately) with each other in an online rapid medium,
2) the online forum is incentivized to make money, and
3) that same forum / business doesn't want the burden of regulating people's speech and behavior
then some Facebook analogue will take its place no matter where people go.
Right now it seems we can only choose to have 2 out of the 3.
