Important part from the article:
Windows users can still change their default browser through the Windows settings.
Almost all of them. Especially corporate customers on managed devices
I’m as pro *Nix as the next person, but be careful of viewing the world through rage coloured lenses. Just makes everything look like a red flag.
Your assuming everyone understands how default apps work. And you are forgetting that most people get intimidated by the popups trying to get you not to change the default.
It is complete enshitification if you ask me. There should be no reason why a application can’t have a button to make it the default.
