Please stop making such statements, it WILL mislead the users here. If it is a grave issue for you, it is better to stay out.
As for others, I will contact Steam and try to clear this out. I still don't have any clue in what might legally be the issue here.

You should first learn to identify statements which are "misguiding" and which are expressing "concerns" , its not a school out here, and no one is a kid to be "MISLEAD" by reading some posts and make irrevocable decisions.
I never said the vault was a bad idea, instead mentioned it indeed was great for f2p and cheap games, my "concern" was that there was NO RELEVANT INFORMATION about other hosts such as origin or blizzard, and then there are informative links where one can read and see that there are mentioning of protocols about sharing library and stuff in Steam too.
I'm not here to advertise "don't use this vault its a crime".
