It was bound to come. MS is probably the last big company to do it.
And it comes down to gamers accepting it. Once general consensus agrees to it, floodgates open and everyone copies.
Absolutely no different than the big change from discs to digital over the years (which for most people even includes needing to buy an external HDD for more storage). A big uproar at the beginning, but now accepted.
Same goes for patches. Console game patching used to be zero. Then during 360/PS3 era it was modest with few patches and they were small in size. Now, it seems console patches are as common and big than a PC patch. Again, gamers accept it so they'll keep doing it even after all the past laughs console gamers used to do to PC gamers how they got patches and consoles need zero.
There's been chat about this kind of stuff in different threads over time. And many of us said the same thing..... if game makers do it long enough, gamers eventually cave in and accept. As long as the game makers hold firm pushing it, gamers always bend.
