There are retro revival consoles that aren’t deliberately made to looks like the original incarnations. I think the issue here was that the consoles being sold were deliberate counterfeits of otherwise valuable original retro machines.

For instance, litigious as they are Nintendo has either been unable or unwilling to snuff out things like the RetroN machines which play original Nintendo and SNES cartridges (and Genesis, and some others) but don’t claim to be a Nintendo machine or look like one in any way.
