I'm always surprised when these discussions happen how few people are using macOS because of Mac-only software. I'm thinking of things like BBEdit or TextMate, Messages, any of the Omni Group's titles, Automator, Final Cut, Scrivener, GarageBand, etc...
Before switching to Mac, I admired Omni Group software. Now after so many years on Mac, I don't use them, I use others. But I agree with you, if your intent was to emphasize how good this software is.
Main reason why I didn't use it, I don't want to be tied only to Mac platform. From this perspective, it was a good hunch. I have android phone, omni focus is not available, others are.
Why not? The text editor by itself might not be what ties you, but how that application integrates itself into the operating system might. For example, you can do some pretty cool things with Automator and BBEdit.
