Most heavy CAD industries are custom. Some likely still on commercial unix platforms. Is a bit like movie firms. The popular view is that Apple has that locked down, but that seems to only be the prosumer market. Most of the main studios have custom render farms that are probably linux based, nowadays. Studios had the motivation to not get locked into large contracts that grow based on the size of their render farm. (Incidentally, this is why Wacom has such outstanding linux support.) That said, fair point on this not being limited to corporate. Not sure why I had that bend from the intro post. I was probably biasing it more to the topic of cloud than I was corporate, but those seem roughly related?
