I view any digital distribution platform where your content is tied to the platform itself as renting rather than buying. Makes things much simpler.

That's why it was so disheartening to buy the x-com remake and find nothing but a steam activation code inside the box. I don't feel like I own that game because it's tied to an online account.

I know that you can just keep a local copy of it, but it's still tied to the platform and if you wanted to go to a different platform, you couldn't take it with you.
