The “opposite” was just referring to those 2 aspects - Mullvad has stronger anti-fingerprinting which leads to more breakage. Librewolf has that aspect reversed. Of course, both browsers are similar overall. That’s just one detail where they prioritize differently.
The question is wrong: it’s not why do you “still” hate Windows. I did like Windows 7. It was the last Windows I liked. After that, it’s just a downhill enshittification spiral. The only real question is: at which point will it be too oppressive for the common user that even the most common user will try to avoid it entirely. And I fear that there’s still more than enough room for MS to make Windows worse before enough people migrate away from it.
