The problem is that the Xbox One's TV integration is the same familiar nightmare we've known for nearly 20 years now. Instead of actually integrating with your TV service, the One sits on top of it: you plug your cable box's HDMI cable into the Xbox, which overlays the signal with its own interface. If you're lucky enough to own a newer cable box, you'll get to change channels directly through the HDMI connection, but most people will find themselves using the One's included IR blaster to control their cable or satellite boxes — a failure-prone one-way communication system that stubbornly refuses to die.
If this sounds familiar to you, it's because it's exactly the same way Google's flailing Google TV platform works. (Google TV even had an NBA demo when it launched in 2011.) If you're a little older it should be even more familiar: it's exactly how Microsoft's own doomed webTV platform worked. We've been overlaying fancy interfaces on top of cable signals and praying for IR blasters to adequately control the boxes for years now, and it's never worked — the content and information on your cable box is too valuable to relegate it to second place, and jumping back and forth between interfaces is irritating and stupid.
What's more, these systems only really work for live television, which you probably aren't watching. Want to watch a show recorded on your DVR? There's no way for the Xbox One to know about it, so you have to use the DVR interface. Found a great show using the One's search and discovery tools and want to record the season? Time to switch to the DVR interface again. IR blaster miss a channel change? The One's guide and channel bar will show different information than the cable box. The cable box is the canonical interface for television, and every attempt to usurp or overlay it has failed.
