You need to read the whole article. It is for Enterprise only and managing an enterprise has a lot of programs etc. that are NOT on the consumer versions. Large Corporations will jump at $7 per user as cheap because it includes Enterprise Support.
Consumer versions are NOT included in this.
The good news is Microsoft has gone on record to say it is not being passed down to consumers at this stage: “This new subscription model is not associated with our current upgrade offering or applicable to the Windows 10 consumer edition,” a Microsoft spokesperson told PC World.

Having managed Enterprise systems for Oklahoma City Public Schools, Bayer Pharmaceuticals, Yale Medical Center, and Hartford Insurance, many corporations will jump at this as a way of reducing staff salaries. Plus they will have the added tax benefit of that $7 per month per user being completely deductible.

I wouldn't worry about Microsoft doing this to their consumer versions. That would cause a huge loss of confidence and loss of users to other (Apple, Linux, Ubuntu, etc) operating systems or even completely stop their users from upgrading to the latest, greatest Microsoft offering (what ever that is). However, I do see the possibility (probability) of MS jumping on the subscription (or subscription only) bandwagon with their "Office Suites" and other software. The Adobe subscription model and distribution is sure to make them want to enter that market.

Linux is looking better and better. I can't bring myself to pay for an overpriced MAC. With the billions of dollars that Microsoft has and the piddling dividend that they finally decided to share with their stockholders, I'm really disgusted with them as a company. Now they want to charge a monthly fee????? What is stopping computer manufacturers from using Linux as their OS? LibreOffice is as good as Microsoft Office and Word Perfect has always been better than Microsoft Office. Sooner or later there will be a 'faster gun' in town. Not a happy camper over this turn of events.
