Also things like selling their loss leaders below purchase price. The kicker is that they still lost the price war they started even though the German discounters kept things legal.
Then there was something about not wanting to publish their balance sheets as they're required to, shutting out the works council from stuff that the works council has a right to be involved in, the list is endless. Not only did they not have a German CEO to manage all that stuff they apparently didn't even have German lawyers.
I expect them to merge enthusiast into the pro segment: It doesn't make sense for them to have large RDNA cards because there's too few customers just as it doesn't make sense for them to make small CDNA cards but in the future there's only going to be UDNA and the high end of gaming and the low end of professional will overlap.
I very much doubt they're going to do compute-only cards as then you're losing sales to people wanting a (maybe overly beefy) CAD or Blender or whatever workstation, just to save on some DP connectors. Segmenting the market only makes sense when you're a (quasi-) monopolist and want to abuse that situation, that is, if you're nvidia.
