Please explain how putting development resources into firstly, porting; and secondly, supporting, a fourth (MacOS, iPadOS, Windows and then Linux) platform that ~1% of non-server computers use works, business-wise? Especially then they're not selling the products for several hundred to start, and moved to a subscription model... From what I've experienced and read, the cost of supporting a platform has to be greater than its sales. The second issue with this is that many people use Linux to specifically avoid using closed-source software. No part about Photoshop on Linux makes sense, from any sort of serious business end. They haven't even done an Android tablet port of full-fledged Photoshop, and I haven't really read any plans to support it. If WINE wasn't a thing, or GIMP wasn't a thing...well, even then; no. This would never happen. XD
