To be honest I think he soft-pedalled how semi-competent Xbox management has been from day #1.
OG Xbox didn't usher in a new era of "multimedia", PS2 being the first cheap dvd-player beat them to the punch. Great hardware but what were they thinking with the industrial design too?
360 was genuinely the high-point in terms of them changing the console landscape, but it needs to be noted that they prematurely killed the OG Xbox to get its head start, and by nickel-and-diming on the hardware they created the entire RROD debacle. Which I don't think gets enough credit as it should for helping Sony exit that long, long generation with much better momentum than should have been possible. Yes, them pivoting to Kinect so hard and the overall lack-lustre efforts of its third party were a big part of it, but plenty of people got burned by multiple replacements of their consoles due to RROD and that must've cost them users.
Xbone... I think goes without saying was a clusterfuck of a launch, and simply put never really got better. It also exposed how bad their studio and portfolio management was.
Then comes GamePass, which was clearly a horrifically flawed idea from day #1. As I wrote at the time there was never going to be a Netflix of Gaming because of the fundamental differences in how we consume games compared to tv/movies. Simultaneously opening a whole other can of worms as to the business realities of maintaining a content pipeline to such a ravenous pit of product churn.
The way I see it, in all their years Xbox has had one great idea: Xbox Live, and the rest has been a catalogue of cock-ups. I see their occasional success outside of that as being as intentional as their failures - its mostly random happenstance.
