@cmdrmoto @LambdaCalculus AT&T and the Bell System were total shitheads and it's reasonable to want to blame them first. Like...that time they sued a company for putting a little cup on phone receivers? Shithead move.
But if it was about kneecapping data transmission on radio, they'd have gone after VHF/UHF, too. Ham packet networks on those bands were massive and used as essential infrastructure.
