I understand if you don't have the CD they can remove your access to it arbritarily like when they lose the license but
Nobody ever complains about Steam and they have a similar policy of no physical media going back decades. I have hundreds of gamed accumulated on Steam and no game of mine has ever been removed.
I bought the cheaper Xbox last year to play Overcooked with my girlfriend and it has no physical media. I just download and play games no problem. I actually find it more convenient not to have any physical games.
So I guess the question is- what is the reason for the strong rejection of the digital version? It is the natural evolution of these things.
