don’t you have the choice to quit?

Many people can't comfortably quit their job. Not in the US. Finding a new job is difficult. Finding a new job that doesn't use Microsoft is even more of a long shot. Most people don't have the money sitting around to just coast without income for very long.

Edit: wow… So many people hate me because I don’t have to use. Shitty Microsoft products.

I don't think that's why you're being down voted. It's the "let them eat cake" attitude about people being stuck at shitty jobs, probably
