I'm from the US. I assume outright beforehand that any private business I have to deal with is trying to scam me, because in my experience they are. After speaking to a few contenders, you pick the one that comes off as least slimy or do whatever it is yourself if they're all completely shitty.
This. I mainly keep Windows around on my old laptop for Office development and I don't need another subscription so won't pay for 360. I'll most likely just stop messing with Office and give Windows the boot altogether. Some of my computers already run Linux (mainly Debian). Office and SubtitleEdit have kept my laptop on Windows 10, but fuck getting ads from the OS.
Dammit... WTF?
