The change where microsoft corporate makes decisions for xbox happened recently after the actiblizz acquisition. Bond has helicoptered in 2017 to work on their BC program which then got expanded onto and Gamepass was envisioned. Before ActiBlizz Phil and co were the decision makers with slight oversight from Corporate, after actiblizz they restructured xbox leadership but stuck to the same people with heavy oversight.So Xbox should be given credit for promoting within, but all staff in Xbox don't make the big decisions. It doesn't matter who get promoted so, so why promote failures and why give Xbox credit for promoting to jobs with no decision making? Your post has a few holes in it.
Bond got promoted because Satya believes in subscription services and she delivered on gamepass which in hindsight has turned out to be a failure, Jim Ryan delayed their plans by 12 months, bitched about CoD exclusivity and really fucked them over. Starfield being delayed was also a big deal, Yes the game turned out to be mid but a lot was riding on it and it was supposed to release in 2022. If starfield turned out to be this generations skyrim then xbox would clearly be in different situation.
In addition remember the series consoles were easily available during the pandemic, My guess is the plan at xbox was to get the acquisition approved in 2022 and sell cheap series S consoles with ActiBlizz games exclusivity hand over fist over the holidays
The thing is this all seems like a discombobulated mess because it is, things have really gone to shit for them since 2023 and they themselves have no clue on how to make this work.
Anyways all this is speculation on my part
