That in and of itself wasn't the problem, the problem really stems from MS taking for granted that 360 owners would all flock to the XB1 but by pushing the angles they did instead of, for a wild example, gaming they basically gave 360 owners no imperative to rush out and grab them. "Hey look, a new Xbox that does all the shit your tv already does" isn't a strong selling point and the CPU architecture swap kicked backward compatibility in the head... They should have been pushing launch titles and xb1 exclusives (those were a thing, right? My memory is getting something something) and all the gaming angles not "hey! Netflix and sport! sport! sport!".
