Microsoft got in the console business when Amazon was still selling books, Facebook didn't exist, Apple was selling iPods and Google was some Ask Jeeves and Yahoo competitor.
Their goal at that time was to prevent Sony from taking over the living room and have Windows there instead. Since then, MS has built a profitable business in a large market. Xbox is now a serious Microsoft business.
However, the landscape in 2023 is much different than 2001. Windows is now a Microsoft side-business like Xbox. No one cares about the living room anymore. Microsoft's competitors have strong ecosystems and have their eyes on gaming with significant investments in it. Apple is probably one of the most profitable companies in gaming. Amazon Luna is a serious competitor to Xbox cloud streaming. Facebook is a leader in VR gaming. If any of those companies got a hold of ABK, Microsoft would be in trouble. Apple worries me. If they got ABK, Sony would be next for them. With that ecosystem MS would be toast.
People who can see the big picture see this instead of some petty console war that will be irrelevant in 10 years.
