Hate to burst your bubble, but the rumor making its rounds, which is supported by Microsoft's own marketing double-speak, is that the "Family Plan" that you're lamenting wasn't anything more than the ability for gamers to allow up to 9 other gamers who have been on their friends list for at least 30 days to access to a 60-minute timed demo of any of their games. After you've reached that time limit you'd be unable to continue until you purchase the game at full price.
Which makes sense. I mean, how in the world could anyone possibly believe that the same company that was essentially trying to singlehandedly kill the used games market until a few days ago was really going to allow us to share our games with 9 other people? Does anyone really believe that publishers would have allowed it when the XBox One's DRM policies were likely in place due at least in part to pressure put on Microsoft by them to help combat used games? I mean, it's not like we haven't heard from developers over the course of the generation about how much they think that the second-hand market sucks for games, so I'm not sure how anyone could have believed that they were just gonna go ahead and sacrifice up to ten potential sales per XBox One to the "Family Plan". Of course they weren't.
The thing that sucks is we'll never know for sure. It's vastly more favorable for Microsoft to just keep its mouth shut on this one at this point. After all, gamers, without really knowing much about it or how it would work, built the "Family Plan" up in their minds to be this amazing, potentially industry-changing feature, so much so the same gamers are now lamenting its loss and are accusing those of us who value our consumer rights of being luddites. So why be up front about what it was when the reality of it surely wouldn't live up to our expectations, and when Microsoft can simply sit back and watch as the tide of public opinion slowly but surely changes in their favor as people get fed up with being blamed for stiffling progress, even if that progress was just a figment of our imaginations the entire time?
