"[A] deeply held philosophical view among many that there should always be the ability to modify computing equipment that you buy"
Parn me, but when did a deeply held philosophical view among many geeks (certainly not among many of the general electronics-purchasing populace, much less the entire electorate by any stretch of the imagination) become a concern for a federal agency charged with protecting public access to the airwaves? I'm looking for case law or FCC decisions.
The convenience and ability to add new features of some RF-emitting designs (and c'mon, folks, you know that even receivers emit some, if only at intermediate frequencies; that's what the standards are for) are good counterarguments to this sort of regulation, but that's a very different argument to/from one based on the geek philosophy.
