I think they're saying that they want to use Linux exclusively. So running CC on Windows is just as bad in their mind as running it on Mac.

(Actually, now I think about it, it's worse than running CC on Mac. Because on Mac at least they get a *nix based OS.)

On Windows you get WSL.

You also get all the baggage that comes with windows.

Very few people that are hanging onto OsX for Photoshop are wanting to switch to Windows.
