And these advantages are meaningful not just for the companies, but for the end-user. Most users don't want to root their own machines, they just want a machine that can help them live their lives, make ends meet, and learn more about their world. A virus that bricks the machine keeps them from doing that.

Of course, for some 15-year-old girl in Jakarta, "learn more about their world" may in fact mean rooting their machine so they can deal with grotty Unix details and 8 years down the road build on that to for an MEng thesis and then startup.
