Ever been on /pol/ these days? It's so much an echo chamber of sponsored trolls and shills I'm surprised any genuine conversation can happen there at all.
Gonna need some hard evidence of that. 4chan can barely sell ads on the site, not sure why anyone would bother marketing to them.
Frankly, 4chan is kind of irrelavant. A couple million weebs, racists and neo-Nazis spread across the world is pretty irrelevant to state actors. No offense to 4chan users, but no one cares what you think.
It's a pretty interesting site, in general, and fairly neat in some ways.
Unfortunately, the best part of 4chan was axed. What was the best part of 4chan? the text boards (aka world4ch): They were less crowded with awfulness, and threads were immortal. It also played host to /prog/, the programmer's chan, which is probably most famous for inventing the now-famous sleepsort (the ancient HN thread: https://news.ycombinator.com/item?id=2657277). Sadly, because threads were immortal, archives were rare, and sleepsort, along with many other threads, has been lost to the mists of time.
Or /b/.
Or most of 4chan in general.
/tg/ is fun sometimes, though.
