>Anyone know why it didn't get market traction?

Oh gee. Maybe because no one sane looks at an industrial product adversarially built to confine and prevent the end user from doing anything to it and wants anything to do with it? It isn't rocket science. If I can't buy it and get a damn manual and programming tools to twiddle all the bits, I'm not adopting. Not even at gunpoint, or if you're the last supplier on Earth. I won't be held voluntarily hostage because a bunch of corporate types, and bureaucrats decided to work together to normalize adversarial silicon. Multiply by everyone I know, and anyone with enough braincells to rub together to pattern match "regulatory capture" and "capitalist rent seeking". You can call me a bore if you want. The incentives are completely unaligned, as this place is so fond of saying. End user adoption is built on faith in product. End user capacity to have faith in the product is based on the capability of the technically savvy purchaser to keep the thing running, repair, understand, and explain it to the non-technically savvy. I look at adversarial silicon isolating me from the hardware; I have to sound off-my-rocker to my non tech-savvy friends family to actually explain that yes, there are industrial cabals out to keep you from doing things with the thing you bought.

It doesn't make any business sense, or practical sense whatsoever. Don't bother quoting regulations that demand the isolation (baseband processors and radio emission regulations) at me. Yeah. I know. I've read those too.

Get over business models that require normalized game theory, and we can talk. Until then, enjoy never having nice things catch on. Hint: your definition of "nice" (where I can't control how it works after purchase) is mutually exclusive with things I'm willing to syndicate as "nice". Nice people don't manipulate others.
