Highly unlikely Apple would cede the software engineering market for a competitor to step in. Almost everyone in my company would prefer to have a MacBook vs a Thinkpad/Dell/etc if given the choice.

If you're not specifically developing for iOS or macOS, Apple doesn't care about you. They'll take your money if you want to write Unix or web software, but they'll drop support in a heartbeat if that makes it easier to support their mobile and consumer segments.
Speaking solely for myself, I do not intend to go with this experiment after using Macs for 16 years and change. I have found that with a few rough edges, Windows 10 and WSL fulfills my dev needs, and except for the Apple apps Logic and Final Cut Pro, virtually all my software is cross platform. Besides, I can use Ableton and Adobe Premiere which I also already "own."
