Even on Twitter I never saw that junk. I followed almost exclusively tech folk, AWS community heros, NodeJS developers, Architects and Platform Engineers.
I’m not even a developer, but I followed them to be exposed more to that topic.
As a result, my feed was 99.9% technical content and product management content.
I got the same result in under an hour with Threads too - just mute every. Single. Thing. That you don’t want to see for an hour and then kill and re-launch the app. You’ll never see politics again.
