The idea that MS should be able make orders that distros then have to follow is insane. If MS breaks something it absolutely is their fault.

No it's not. Microsoft has to disable outdated and vulnerable signed bootloaders to stop them being used for secure boot bypasses. Microsoft worked with RH to get things updated which they did, it's just distros for caught slacking and were shipping an outdated vulnerable boot loader.

I know it's the norm to bash Microsoft and they do a lot of crappy things, but in this case it was just certain distros not taking security updates seriously, which is why a lot never broke (such as Fedora)

So Windows installs something that brakes Linux boot. How are you supposed to boot Linux to install a fix? Am I expected to reboot into a different OS twice a day and check for updates? Am I slacking for not doing so?!

No, Windows updated a UEFI component that disables outdated and vulnerable bootloaders to stop them being used as secure boot bypasses.
