I'll say it took a VERY long time for Xbox to fail like this. If it were Playstation or Nintendo with this history, everyone would say it was a "crime against humanity" to let them buy Bethesda and Activision (referring to Halo "Monkey" Craig and the "12TF" crap that can't beat the PS5's 10TF).
The internet and consumers were VERY patient with Phil Spencer; perhaps because they thought he was "the poor, good guy in the gaming world" and Xbox the underdog.
The best example of Phil Spencer and his subordinates' true competence is seen with Halo Infinite and the "12TF full RDNA2" Xbox.
They don't know how to build hardware, celebrating for a whole year with "fixed clock speed," "full RDNA2," "sustainable performance," and clearly they DIDN'T know what they were talking about.
In the software department, we had the Halo "Craig" Infinite fiasco... the Xbox box even had Master Chief on it... That's the biggest fiasco in console history.
I'm amazed at how complacent people are, and many are perhaps bought off, by the Xbox.
Every week there was an "article" saying that Nintendo would go bankrupt and become a third-party developer because of the Wii U.
Even today we have the "arrogant Sony" because of the PS3, and it's been almost 20 years since that happened.
That clown Phil Spencer messed everything up with the Xbox Series X and the games, and people were like, "Oh, it's a good idea for them to buy Bethesda and Activision." Phil Spencer NEVER knew how to make games or hardware, and when they got it right, it was by copying Sony (the Xbox One X is much more similar to the PS4 than the Xbox One) or pure luck.
