This extends to a lot of politics these days. There are well-financed parties out there whose goal is to destabilize, mainly targeting the US and Europe but I'm sure it happens everywhere. These are the ones behind Trump getting elected, Brexit proceeding even though only 28% of eligible voters voted in favor of it, the referendum being bad for only having two options, and the referendum only being advisory, and countries like Hungary and Poland shifting hard to authoritarian right, breaking with the separation of state and justice.
These forces have the destabilization of post-ww2 unions in mind on the one hand, and people focusing on each other internally instead of internationally on the other. Think things like JK Rowling's trolling, Trump coming out with something that all of twitter and the media pounce on, Reddit brigades.
I feel the same way! When they come up, my reaction is "nice"+cmd-w. Thanks, twitter!
To your response: I mean, there are some curious people on twitter. Curious people don't engage in the problematic dynamics outlied in the article, so some exchange of information happens there. That's clearly not representative of the bigger picture though, simply because the most people can't afford curiosity, courtesy of their cognitive functions (if you subscribe to Jungs model) and/or their position in maslows pyramid.
