Assuming that there is a difference and it's on the "wine side", rather than the original developer having anything/much to do with it...
You don't need Photoshop in the same way that you need a particular game. There's only one piece of software that provides the (e.g.) Death Stranding (strandlike) experience. There's any number of tools you can use to do most of your favourite Photoshop usecases.
Conversely, Photoshop and Illustrator support is often the reason someone maintains for not moving to Linux. I would bet there's a lot of Mac users who would otherwise be Linux users if not for that lack of support, and instead went to Mac. It's the only way to have comfortable Adobe support outside of Windows.
Only a small percentage of the PC user base uses Photoshop. Its visibility in this sort of discussion is all out of proportion to actual utility. This is especially true once you snip out the number who use pirated Photoshop exclusively to do simple operations like cropping and resizing.
Want to have more users work on the stuff that matters to 99% of users instead of nurturing a hope that people might give up their Macs.
For some it's Photoshop, for others its Solidworks, for others it's some other niche software like maybe driving an industrial machine. The niche market is very long tail.
