Has nothing to do with technology limitations. Has everything to do with idiocy around revenue maximization and good old fashioned arrogance. It's why I made the Steve Jobs reference. For all his flaws, he was uniquely talented at recognizing customer-antagonizing idiocy and doing something about it bull-in-china-shop style. That's what the cable, satellite and broadcast idiots need. They haven't learned from what happened to traditional book publishers and music labels. Their day of reckoning is coming. Our grandkids won't have to deal with this stupidity. The existing model is unsustainable.
