You can jailbreak the console, but you have to be on system software at least couple of years old or so. And ofc do not connect it to the internet, then you can pirate all the games you want. Check out modded warfare channel on youtube, there are various exploits for ps3/4/5 and he explains how to do them well.
World without borders, is the world without escape. Now we have different jurisdictions, which limits the reaches of power of governments. You can move to a country with less oppressive laws, or at least get news from there. Different jurisdictions makes things like TOR and VPN work for censorship circumvention and privacy.
Besides earth federation would subvert any diversity we as humanity have. I would prefer more small countries gaining sovereignty than big empires(federations) growing. Power should be decentralized, not the opposite.
Not surprising for them to drop MV2, I expected it to happen even sooner, you would have to go out of your way to support MV2 extensions on chromium based browsers, and I do not see a reason for Microsoft to do that.
I get the impression that people want MV2 primarily for better ad/script blocking, but maybe the more secure and efficient way to go is to have built in adblocking. Firefox recently integrated adblock-rust, but you have to enable it in about:config and add filters manually, it seems very experimental and barebones at this moment compared to how it works in brave, for which it was written originally. It is probable some firefox forks expanded on this feature.
