But the problem is Adobe Lightroom CC has effectively zero penetration with professional photographers. If I had to summarize the pro market opinion of CC, it would be contempt. Here's an example: This article (https://petapixel.com/2020/01/02///why-im-sticking-with-ligh...), about choosing Classic over CC, has about 100 comments, the maximum allowed, most panning CC. Of those 100, it's easy to find the single positive comment about CC: it's at the bottom, with the most downvotes.
The problem is the whole basis of CC (cloud storage) is antithetical to how professional photographers work (thousands of large photos per shoot). Adobe can't grow CC into eventually supporting this market because it can't support offline storage, because the whole reason CC exists is to have a product that's cloud only...
So I think Adobe will effectively be supporting Classic forever. Here's an example: Adobe has committed to native support for Classic on Apple Silicon (https://helpx.adobe.com/lightroom-classic/kb/macos-big-sur-c...).
