As someone else said, it's a patent. Nothing is a feature of the Xbox One.
Also this would be available to the content provider, it isn't necessarily automatic. If 20th Century Fox/Disney doesn't care that you have seven people watching Star Wars: A New Hope, but Sony Pictures wants to charge a ticket price for each viewer of Spider-Man, than it would be Sony Pictures that you'd want to bitch about not Microsoft.
Where this could be cool is, let's say a movie studio decides to make a Block Buster movie available for home viewing on the day and date of release in theaters. So for a ticket price of whatever theaters/cinemas pay to studios, you can view the movie from your console in your home. But as with a theater/cinema seat, everyone pays a ticket price if they're there watching the film.
That would seem like a good use for the technology. Doubt it'll ever happen, because I don't think you'd see that with a blockbuster movie but rather something intended for direct-to-dvd or direct-to-on-demand., but we can all hope and dream.
