As long as the devs have an instance-agnostic 'live and let live' attitude and just ignore any instances they don't politically like and advise others to do the same, it's not really a problem.

If they ever try to enforce their ideology via their code: actual issue.

(for me the main one are the tankie scum devs)

This right here is the crux of the problem and why the problem goes back so much further than the design and algorithms of platforms. We teach kids to focus on individual achievement, to celebrate the self, and we don't teach empathy, something that needs to be taught young and can easily be taught but the west increasingly considers weakness and a dirty word.

When we fail to teach citizens of a society collectivism, because being a member of a society means you are part of a collective whether you decide to be a good collective that functions or one that operates against itself (herp derp competition!) that does not, you get communication between members like this.

"I hate these people fuck them they should me more like MEEEE" "their opinions suck because they aren't more like MIIIINE" and we act as a bunch of petulant infants that resent each other's very existence in OUR world.

If we were taught that it is our responsibility to lift one another up, if we rewarded people in society on the basis of who and how many others they've helped and not how much they hoarded for THEMSELVES, this wouldnt be as much of a problem. We could, now that we don't have to survive in nature, orient our mindsets to the positive, which would have to be encouraged young. Instead we're made to be like... This. A useful state for killing a rival in YOUR hunting area when there's only enough game in the region for one tribe to survive the winter, not so much when trying to build a civilization up. And don't get me started on the counterproductive mindfuck that is nation states and super serious imaginary lines between them, meant to protect hoards of INDIVIDUAL wealth of respective elites.

The problem is, how do you start such a virtuous cycle when everyone from the owners down are only concerned with "ME ME ME MINE MINE MINE?"

Then again you hate tankies, so go ahead and cuss me out for calling out the reality that capitalism, especially when it has effectively conquered the culture, turns people into selfish little gremlins more likely to shoot a stranger than help them.
