It'll probably end up worse than that. Turn off secure boot and Windows may still run, but it will no longer verify and all these sites will now refuse to work on your computer. So if you like to run Linux, even dual booting or running Windows in a VM for those things that absolutely require Windows won't be good enough anymore.
Personally, I didn't really mind Wesley in the later seasons and a few of the Wesley-centric episodes were pretty good. It's really the first season, and even more so the first few episodes of the first season where he was annoying as all hell. Oh look, boy wonder saves the ship, yet again. Unfortunately that kind of seems to have stuck with the character, despite the show toning down his antics significantly after that.
