It only sounds like propaganda to the ones intentionally & knowingly staying who, in turn, only become the majority once the average users have already been pushed off by such things. In net, dropping official support claims for unpatched targets is a good even if it annoys users who already understand the situation clearly. But yeah, nobody should be going into someone else's computer and force deleting an app "for their own good" or something - that'd be pretty hostile.
And, again, it's only just part of a joke here. The entire debate about how a subset of Windows 7 users could be annoyed if it had really pushed this support reasoning message seriously is all theoretical from the comments section. It's exactly the type of "a minority of users might get really worked up about any perceived sleight around the topic" kind of thing one finds in this area - you can't even make a joke involving it being a better reason than playing a game without resulting in discussion and someone technical bringing up how hostile it is to make such a mention.
