Navalny most certainly wasn’t stupid. He understood what he was getting into when he got on that flight back to Russia. My guess is that he hoped his arrest and detention would spark an uprising, which sadly didn’t materialize.
I would not have made the choice he did, but I’m also not as brave as he is. Fuck Putin.
I just watched this YouTube video last night of someone setting up Bazzite on a mini pc to create a sort of Steam Machine, might be nice to check out. https://youtu.be/f45hDPOrzFI
