alt Hacker NewsThe openness of Android also acts as a check of sorts on how restrictive the walled garden can get. If google were to clamp down on useful functionality in the play store, then you could always install apks yourself. But if the latter is no longer an option, then there's much more temptation to google for the former.
I get the feeling that clamping down on useful functionality is often an unfortunate side-effect of closing down paths that are being exploited by criminals to harm users.
What should Google do when a change they are making to protect regular less-technical users breaks functionality needed by more advanced users?
