Thank you.
Nobody truly interested/invested in “subversive activity” (heavy on the quotes there) is going to go blabbing about it on the frickin clearnet.
Just because you don’t see things posted online doesn’t mean they’re not happening.
Life exists outside the internet and even in Star Wars the rebellion didn’t go screaming and drawing attention to what they’re doing. Neither did the Empire.
Any real change, in any meaningful direction happens in meatspace. And most people who aren’t in the status quo party(ies) are going to keep low in public when not in huge numbers. Hard to do anything impactful when you’re dead or disappeared.
