Microsoft is one of the biggest game publishers, given the amount of AAA studios under the Xbox and Microsoft Game Studios organisation.

Great point. Exactly. They have undermined the marketplace by hovering up and consolidating studios, scuttling a lot of IP that gamers care about and squeezing money out of properties for quarterly gains. They use their market power to push worse games with abusive, dark patterns. Microsoft has really become even more of a heel than they were in the 2000s.
