I mostly mean the common criticisms of Google for incentivizing web spam, and Facebook for pushing low quality / addictive / political content into people's feeds. (Though if you ask people outside the tech industry, they might not agree on these problems!)
The counterargument is that they both provide a ton of value, they didn't take anything away, and you don't have to use them. (defense of Google - https://news.ycombinator.com/item?id=39054621 )
There's some truth to that, but it seems like we could be past peak social media (?) It feels like people are kinda treating it like smoking -- it was a poisonous fad that went too far, and it's wise to dial it back.

Curious to know more about what you mean by this, if you have the time... poisoned how? cheers!
