Sigh. That's perhaps the most crazy statement I've read today.
When you have several hundred workstations, over a thousand HPC render machines - Windows tends to become a bit pricey. For VFX, Linux *is* the industry standard platform. 95% of the standard 3D modelling and 2D/3D compositing systems run on Linux. You must remember that SGI's IRIX was the dominant OS of that industry for a long time until commodity hardware and Linux took hold and replaced it. SGIs soon became bricks and doorstops.
Photoshop was one of the rare exceptions. Disney and a few other facilities contributed funds to the Wine project to develop it sufficiently to allow Photoshop to run well enough under Linux using the Wine system. Ultimately as hardware got cheaper, VMs were a better solution. There was no other application - open source or commercial that could match Photoshop's feature set. There are one or two other products that required Windows. These were used by a very small number of artists out of the several hundred coming and going through the facility.
I work for a web hosting firm now. I'd say the majority of all production web sites and applications that we and our customers are running are running on virtual machines. I've been using VMs now in live production environments for years and I couldn't disagree more with your statements.

could not agree more, you have taken the words out of my mouth/keyboard
