I understand.  It just seemed you were explaining why PPC is no longer 
supported as the natural outgrowth of software development progress.  I 
mentioned Debian both because I'm curious if anyone runs it on PPC, and 
also as a counter-example to the type of development model Apple uses.  
(One which is able to support a much wider variety of architectures at a 
fraction of the cost.)

A longer discussion of OS politics is probably an unnecessary digression 
here: both you and I are building things in OSX, and that won't change 
by pointing out differences in our philosophy for why we do it.  But I 
just wanted to point out that "use what works for you" should expand to 
"use what works for you without creating a moral hazard for all of us".  
One doesn't need to use the language of free software advocates in order 
to do that, but free software is undoubtedly part of any viable solution.

If the internet that connects all these devices weren't actively being 
weaponized I probably wouldn't quibble over this.

Well, I might, but it'd feel more like a pasttime and less like a 
necessity. :)

Ok, that sounds like the way to go then.
