There are probably way too many people (the majority of their fanbase and all the computer illiterates as well as the moms and dads who get it for little Jimmy after he whines for 3 months straight) that will just pay for it without a second thought for this to be a bad move for MS.
The people who would get mad enough about this to not buy an XBOne/Live are likely the minority or the people who were not even in the market for a console anyways.
You think so? The idea of gamers - including console gamers - as 12 year old kids who rely on their parent incomes is massively outdated these days. The average age for a gamer is 32 in Australia, only very slightly younger that the average of the entire population. In other words, while it skews young, the gamer demographic is almost representative of the community as a whole. And remember, the average member of the community might not be as computer literate as the average PC Gamer is, but they are at least somewhat aware of the significance of lifetime cost vs up front cost - it might not be something that is generally thought about in games or consoles (at least, not as much as, for example, houses or cars) but the concept is there, and I think it does a bit of a disservice to people to just assume that it isn't.
And don't forget, almost nobody buys anything worth more than a few bucks without looking up reviews for it online first. If people are choosing between the XBox and the PS4, they're going to look up reviews, and - especially if they're looking at generic electronics sites as opposed to gaming specific ones - reviewers are going to mention any ongoing costs. This really could hurt Microsoft, if Sony are clever enough to exploit it.
The "kid gamer" was really just one example, but not what I would base my argument on.
I think you overestimate the amount of people who are willing to research what they buy.
Don't take me wrong ... I do research stuff heavily as well, but always had the impression that I am definitely not the majority.
And generally speaking... the more money people have the worse it gets. (I.e. especially people in their 30s + with a regular income and "fun" money to spend.)
When talking about the mass market, the informed consumer is a myth.
If anything, it's all about hype and advertising to get into peoples homes ... but hardly about factual articles.
