They don't necessarily have to: there's another, more comprehensive hammer they (or the US for that matter) could use: disallow vertical integration. Force hardware vendors to only sell hardware. If any software that can be changed remotely or by the user is off limits. Even firmware. Conversely, software vendors can only sell (or freely distribute) software.

> either they only sell hardware in the EU, or they only sell software. Intel and microsoft would have no problem. Intel has microcode. Microsoft has Xbox which I'd guess would have issues getting game releases if excluded from a decent-sized market. Also. My phone (hardware) came with an OS (software) already installed. As do other pre-assembled computers.
I'm willing to sacrifice the business model of game consoles.
I hate OEM deals, it just propagates the current monopolies and oligopolies. I'm okay with forcing everyone to buy their phone or laptop separately from the OS.
