I guess it all depends on how picky one want to be.

Before the generation of consoles that includes the xbox, I can't remember of any real attempt to lock them down by preventing unsigned code the be run (and I don't consider not releasing an SDK really a walled garden).

I also don't remember Windows Mobile preventing people to run homebrew code and Symbian enforced signed-only code roughly when Nokia N82/N95 came around.

Anyway, locking some API/functionalities is different from requiring all code to be signed which in turn is different from requiring that all code must be distributed by a single entity (that can apply arbitrary terms of conditions to distribute it).

Although In logic "slippery slope" reasoning is a fallacy, in -real-life, it happens all the time. Draconian rules are introduced one step at a time so I still think that was about the right time to vote with your wallet.
