I'm pretty sure that most go with habit and convenience. I mean.... Apple could lock MacOSX down tomorrow and charge you $100 for terminal access and "informed decision" people would still argue how good MacBooks are (they aren't that good)
I literally have to have an app to make my bluetooth mouse scroll in the opposite direction than the trackpad, because there is "Scroll Direction" checkbox in both mouse and trackpad... but it's actually one config option. And with every update I hope that they don't screw up that app... OSX has less and less of "less is more".
It's a mutually-beneficial trade-off, it's just that one party gains individually, and the other gains by quantity. Advertisers wouldn't care a lot what restaurants you like, but they care a lot about what restaurants people in your city like.
