Why do you assume people posting there have any agenda? Heck why should everything on the internet have an agenda or end goal? That subreddit is a large-scale collection of "I told you so" Facebook posts, as you said, and that's it. It isn't some vaccination campaign. People can take whatever they want out of it. Darwin awards have been a thing for a long time and are part of internet culture.

The material there isn't what's wrong with the internet, rather all the calls for "xyz should be shut down" for anything slightly offensive to someone's sensibilities are the problem. If you don't like it, close the browser window and move on with your life.

Of course there is an agenda behind it. Pro tip, the name of the subreddit is a bit of a clue.
