The worst offenders, in my opinion are operating systems. Every time I start my computer I get an annoying prompt to sign into iCloud, which will reappear immediately on cancel, so I end up having to close it about five times. Apple is trying to browbeat me into using their service by being as annoying as possible. At this point, even if iCloud was great I wouldn't use it on principal. Microsoft is even worse, not only do they have their own annoying cloud "features" they opt you into, now they've decided to administer your computer for you from afar. I had to wait an hour yesterday for Windows to install a giant update that requires multiple reboots because they tried to install it overnight. Worse, it was applying it at the boot screen, so I couldn't even pause it or read the web while I waited. If Microsoft can just put my laptop out of commission for hours on a whim, with no warning, I can't trust their os for anything important. I'm not a Linux fanboy in the least, but since both major os's make me feel like I'm just renting my own computer I might make the switch.
