In the role of dev workstation, I'd personally be willing to switch to Linux, at least as a protest vote. As a target OS to sell software on, a pragmatic vendor would be less likely to abandon it, agreed. However, if in order to ship a Mac app, you not only had to only distribute through the App Store and also could only develop with XCode, Objective-C, that whole inane overly complicated bureaucratic software development rat's nest, then I for one would abandon it, definitely. I currently sell downloadable Python-based software, written in vi, with no insanely overly complicated build, approval or distribution process, and it works just fine, thanks. If they forced me to jump through many more hoops, and over-complexify my software, they'd lose me in a heartbeat. That's a line I will not cross.
