Fun fact though, photoshop used to be available for solaris http://www.erimez.com/misc/Photoshop_Sun_Brochure.pdf

Yes the same reason for the past two decades

If anyone from Adobe is reading this, I would use CC with subscription on linux and advocate for licenses in my whole office if it was an option

Cheers

You didn't get it right? Most of the customers who would switch are already using CC on Mac or Windows so why add the costs of maintenance and support for another platform.

Aside from that, their code base is somewhat quirky, which would definitely increase the cost of porting

I understood what you said exactly and thats why I also added the part where new licenses would also happen as a single customer datapoint accessing many organizations over my career. The more datapoints for them the better.

I look forward to the day when Krita or GIMP’s sole purpose for existing isn't Adobe dug their own hole.

Can't speak for GIMP but Krita is growing exponentially, :)

Ohh my bad

Can't disagree on anything you wrote. But if they leave an unfilled hole, the competitor that kills them could emerge from that hole.
