I’ve been paying for OmniGraffle since 2004 or so and also bought licenses at various employers. The price has never been a problem.

But if it wasn’t a native Mac Cocoa app, I would never use it. A lot of OmniGraffle’s value comes from UI that abides by platform guidelines and the high-quality rendering and integrations enabled by being a native app rather than a lowest common denominator cross-platform port.

The difference between using software developed explicitly and exclusively for the Mac (and/or iOS) platform vs a cross-platform application is often quite dramatic.

Omni in particular makes extremely clean, friendly applications that feel aligned with the platform.

Yes. I would pay for a native Mac experience. I would never pay for any app that uses something like Electron. If you’re okay with mediocre software, why buy a Mac outside of doing development?

The way things are going you're not really going to have a choice in a few years.

We do have a choice now, and that is to pay for good software. When we resign ourselves to "the way things are going", it tends to be a self-fulfilling prophecy.
