Re: Walled Garden? Really!
"The Walled Garden has many exit doors."
It might have a few pre-approved exit doors, but it has no entry doors. You can't install the apps you might want, only the ones that are chosen to be placed in the central, and only, repository. So long as they follow arcane rules that may change and/or be applied randomly.
Or, as the above poster says, it's a bigger box taped shut.
