Phil took over in 2014, he needs more time.
He made significant changes.
He killed Kinect, that was Don Mattrick's vision with TV TV TV and DRM which was the major crux for Xbone.
He pioneered the BC program. Everyone said it couldn't be done, heck Sony didn't try, but Xbox 360 BC and even as far back as the OG Xbox is definitely great and seemleess.
He gave fans Scorpio which was sort of "Make up" for the disaster that was Xbone and it delivered, it definitely beat the PS Pro in every way.
Xbox play anywhere, slowly integrating Xbox and PC is a good thing that now even Sony is copying bringing their big titles to PC.
But the 2 major things that Phil pioneered was convincing MS to spend BILLIONS of dollars on the Xbox brand. MS spending billions to purchase game studios is a testament that they're taking Xbox as a serious investment. The 2nd is putting all chips into Game Pass which could make or break Xbox, but so far for gamers, I can only see it as the best deal in gaming, opinions be damned.
Turning a ship around takes time, a generation is now about 7-8 years and all of the investment spent is likely to have fruit next generation, THIS generation is when all these changes are happening and it takes a minimum of 5 years to make the simplest game now a days, so some people have no idea what they're talking about when it comes to a timeline, major changes are happening AS WE SPEAK! LOL.
