It is a grey area. Right to repair has had success without legislation for abandonware. The rights of the copyright holder generally don't actually extend to blocking your access.
Now whether "latest Intel chips don't support playback" is sufficient to fall under this flag is obviously a complex topic but I think it is certainly not cut and dry.

The issue here is that the DMCA makes bypassing copy protection illegal regardless of whether or not the actual use of the media infringes on copyright, and exceptions are only added every 3 years[1] and are generally very specific in scope.
From my understanding it's less of a gray area and more of a dithered black and white area that can look gray from afar.
