>Now Windows 8 (moreso RT, but even the x64 version) and Mountain Lion are moving to the walled-garden, segregated, impotent app approach

What can't you do in ML that you could in OS X 10.1?

If and only if the app signing and approval by Apple gets mandatory to run apps, a la iOS, then you'll have a point.

As for now, all the new signing etc are additions on top of the regular infrastructure, and the reason they were added was security.

Most security nerds find app signing and sandboxing a good idea.

Those same security nerds have been doing both on FLOSS operating systems (BSD, GNU/Linux) for years, so that point is irrelevant to the original discussion.

Which is not the same at all with having thousands of proprietary third-party apps to distribute in closed source form (as opposed to having control of some open source repo with redistribution and re-compile/modify etc) right.

So your point is even more irrelevant to the original discussion.

What are you talking about? Nothing about app signing and sandboxing requires open-source repositories.
