If Google is paying Apple effectively not to make its own search engine, I would not be surprised if Apple and/or Microsoft were paying Adobe not to port CC to Linux.
I don’t think we need a conspiracy theory. Most likely they don’t bother with 5% market share, most of which probably have strong feelings about closed source in general and Adobe in specific.
Wasn't Mac OS less than or around 5% for a long time after the 90s? If they thought that was sustainable, maybe Linux should be close by now? Of course there are many other things to also take in account, so who knows.
Most apps started on the Mac, so there was no porting needed. Also, most professionals had Macs, so Adobe had a 50/50 revenue split between Macs and Windows, even though there was a huge market share difference.
