I'm still using good old PC BIOS partitioning, dual boot Arch and Windows 10, and after every single Patch Tuesday I end up having to manually change the boot partition, update Windows, then use third party Windows software (because Microsofts built in tool wont let you set a partition containing a filesystem they don't recognise as active to switch it back to Archs /boot .
I rarely boot in to Windows 10, but very single time I do now its a 5 minute update, rollback, reboot dance. I just don't know how you could call this 'FUD' when its been painfully obvious for 10-15 years that Windows Update is about as broken and agonising as it gets.
And, while I am a 'Linux fanboy', I also have a Mac... and Apple manage to make updates a joy.
Furthermore, if you rarely booted Linux or your Mac - you'd have a lot of update problems with them too. In my experience, Linux Mint will literally shit all over itself when it tries to update, if you haven't constantly kept it up to date for some reason.
With Apple, if you haven't updated in a while you might be in for a good 30-60 minutes of fighting with their updater to work properly. Besides that, Apple does weird shit with hardware during updates because of the extreme measures that they go to in order to keep competitors out. That's why there has been a plague of issues with 3rd party (and even 1st part) hardware dying during OS X updates - https://www.google.com/search?q=os+x+mouse+not+working+after...
Apple also delivers silent updates - https://www.google.com/search?q=apple+silent+updates
EDIT: Also, your story conflicts itself. Is it "every single patch Tuesday" or is it "I rarely boot Windows 10"?
Anyway, you should just fix your configuration to one that is supported by Microsoft. Would you run a hardware configuration that isn't supported by your Linux distro and then complain about it when it didn't work? No, you would not. And if your reply is that "I'd fix it myself..." - no you probably wouldn't. If you're one of the rare few who actually would, then you're spending the most precious resource that you have in order to do it - your time. In that case - I hope you enjoy doing it! Me? Like many people, I'll take convenience any day over ultimate flexibility.
They don't need to cater to them, they need to NOT block them from doing so, because they're a monopoly in this space.
Microsoft doesn't need Linux desktop barely anybody runs it.
