Here's the (a?) kicker: advertisers are willing to pay orders of magnitude more to get ads in front of group 1. They'll pour so many resources into it that they'll make everything "worse"* for group 2. Group 1 adjusts their filters (both technical and mental), get back to neutral, but the rest of the internet is just a little worse off going forward because advertisers and publishers saw a very slight up tick in clicks after their scorched earth campaign to reach group 1. Rinse and repeat until we find ourselves where we are now.
I used to think that over time group 2 members would trickle into group 1, sort of like how programmers and hackers were using Google before it was cool and slowly the world followed, but that doesn't seem to be happening. Personally I'm seeing the groups continuing to divide. Group 2 really just doesn't see the problems, doesn't care, or isn't willing to put in the slightest effort to improve their interactions with technology and the internet.
My "favorite" outcome of all this is when a member of group 1 is forced to use a device owned by someone in group 2 and are horrified at what they see (favorite because it is equal parts sad and funny).
* "worse" in quotes here because group 2 doesn't seem to notice or care about the slow decline into madness.
