Let's talk short but direct about Steam (and other so-called platforms offering software-entertainment): Within a newly released claim it is now clear to see that people only give money for "the right to use software within given rules companies and the platform itself are able to change at will". So in fact: People are renting software, not even buying any license. And this is not the only platform: Battle.net, UPlay and so many more acting the same way. No right to "own a license" but only to pay for using until others forbid this. And the best aside: People around GNU/Linux telling that Steam has brought so much and Valve did so much. Yes? Please, tell more fairy-tales. Valve is only doing this for their own purpose. To own the people, enforcing them staying on the platform. Same as others have done later on also with other named platforms. We do not "own" software, we do not even "own" a license for usage. We just pay for renting something, not even a right to use. Just paying that amount others tell us doing so.

And what about the software? Well, when the owning persons and institutions decide the software should be no longer of usage, they just cut off people using it as they do not "own" a license, just the current "right to use" - with the option to loose this at any given time. And then the software itself is forgotten as of no longer usage for earning money. A brave new world!
