My guess is, those auto installs is exactly how they keep the costs down, by subsidizing the cost with getting paid by companies to auto-install garbage. It's the same with Smart TVs, they've gotten so cheap because of all the other slimy stuff the manufacturers do, like sell your watch data, or pre-install apps.
I've heard this theory before, but is an individual data point really worth enough to make this argument?
