Strictly speaking all software licenses are already 'a right to use' not ownership. But I hear your concern and you're not alone in worrying about the direction. Luckily there are alternatives, even free ones.
My concern, combined with the lack of knowledge with most end users, are the primary reasons I will not recommend Windows 8 to anyone. Secondary to that is the lousy GUI. Next you will be driving your computer with a mouse, a keyboard, and a touch screen. Sounds like a lot of work to me and not a lot of fun.
