I agree, but history just proved that Apple does not care.
And let's be real: Photoshop is cross-platform, and lots of content creation software is cross platform (or a web app). There are many more content creators that use Windows than people here are aware of or want to acknowledge (on HN, sometimes you get the impression that Windows is a forgotten OS that nobody uses). Now, Apple is at a huge disadvantage for losing that market -- often you can only be a big player if you have enough users. Apple also is never known for putting apps on the web like Figma and doesn't appear to have plan to do so.
A similar example is the iWork suite. It exists, but neither users nor Apple seem to care about it.
In the end, they just kind of development native Mac OS software half-mindedly. Which is fine -- that's what they want to do.
