Switching from gmail to another provider isn't like living without electricity, it takes a couple of days updating some external accounts to reflect your new email; I did it.
Buying shit from somewhere that isn't Amazon isn't exactly trekking through the jungle for 3 weeks. All you have to do is type in another domain. There is no shortage of non-Amazon sellers with similar prices.
Switching from Chrome to Firefox takes 5 minutes, you can import your bookmarks and whatnot. Maybe you'll have to type in a password again. No climbing K2 level difficulty there either.
Android and iOS aren't that different, you can click a browser, camera, or email in either in the same amount of time with the same UI.
Sure it's effort, but it's not a hell of a lot of effort.
