Smartphones are general-purpose computers with a bunch of little digital locks, that while strong, are not impervious. Such locks, when used to protect a device owner, are good. The same type of locks, when used to deny a device owner full rights to use their device as they see fit (absent harm done to others), are evil.

mtl is saying computers are big boxes of math and you can't ban math.

Though given how incredibly clueless politicians have become I wouldn't be shocked if they tried.
