It is an issue on game consoles too, just because it has somehow become accepted it doesn't mean it isn't an issue that you cannot run whatever you want on your own hardware. "Others are doing <bad thing> too" isn't much of an excuse.
Also note that it isn't all game consoles, there are various open game consoles, though since they are not made by huge companies with huge marketing budgets they are not as popular (perhaps Atari's new Linux powered console[1] will change that, but we'll see). However their existence means that games consoles are not synonymous with locked down walled gardens.
It's almost as if there is a very large hacking scene for game consoles because people want to run whatever they can on the hardware they bought. Let's also not forget the whole Other OS fiasco with the PS3.
I'm sure if the next Xbox had the ability to run Windows 10 it would sell like crazy.
