Their family share plan was extremely vague, and only mentioned being able to share with ten other people who would probably have to be family members. If they were so dead-set on having this feature in the first place, why didn't they give any solid knowledge on how it'd operate? The reason why there's so much misinformation and speculation going around, is because Microsoft is being intentionally vague on their features. I highly doubt they're so idiotic, that their PR department (Which they probably put a majority of their money into) would fail to realize people would want hard facts on new features. Chances are, their ideas and implementation were vague, and they just wanted to see how people would receive various features.
Details were confirmed over twitter with people asking. All you had to do was search twitter yourself or check Xbone news outlets that weren't just copy-pasta IE the /r/XboxOne/ subreddit. The reason there's no much misinformation going around is because of the CircleJerk explosion. The people didn't have to be family members either. They could be on another continent. It was an arbitrary designation.
No I also think they're not stupid, but that being vague on these sort of things is standard procedure. Sony danced around a number of questions like the restrictions for 3rd party titles. Guess what? They have/had the EXACT same policy as Microsoft while claiming to be better. Yes Microsoft could have been more specific (designation of family and library access worded a little ambiguous), but the terms were still laid out FOUR DAYS BEFORE E3.
Oh no but "It can't be real."
Edit: Oh, and yes. Any misinformation or negative opinions are OBVIOUSLY just propaganda spread by a specific website. That makes perfect sense.
I literally could not post cited information anything on chan, reddit, or misc forums without getting:
"That's false [I heard X from 4chan, NeoGaf, /r/gaming, etc] [insert copy-pasta 'infographic' with no actual citations from Microsoft]"
"That's too good to be true it can't be real"
Steam isn't bad
No, Steam does it's own thing. The only reason it's accepted is because of the sales, and there are still many people that hate it for the DRM regardless. The used games sharing/reselling/etc would have been an alternative model. I like having alternatives, just as you like also having Amazon, GOG, etc.
