>Also, FU everytime something is just built for macOS. It's such poor stewardship (at the very least for everyone who isn't Apple) to reinforce the walled garden that is macOS.

Really? If the non-walled garden of Linux is so wonderful, what's your problem? Other people shouldn't write the software they like for the platforms they enjoy?

I like to be able to depend on a software with commercial ties, that doesn't change when some community gets bored and has different whims (e.g. "let's redefine everything people know about Gnome 2", or "let's write the n-th audio framework").

And that also attracts major commercial packages like the Creative Suite, DAWs, VSTs, etc -- stuff which I depend on, and with no real match on FOSS world.

Well, I understand why one wants to use a native GUI toolkit (Cocoa) instead of a more generic but cross platform one (for instance Qt). GUIs just feel smoother. This has always been a thing for Mac OS applications -- but interestingly never so much for Windows applications, because look and feel was always prioritized in the designer-addicted Mac world. I like that -- the Mac UIs always used to feel high quality and polished. Nevertheless I'm a 15yrs Linux user and pay the price of the Gtk/Qt "uglinesss" for my freedom (it's not so ugly any more :D ).

Do you believe developers think: "I could make a lot of money developing software for Linux but I'm not going to bother because I love walled gardens."?

Or do they perhaps think: "I can build a viable business on MacOS so that's where I'll invest my time and energy.".

Do not use it then.

Applications should use the native GUI APIs for the OS they are running on, native GUI APIs are not there for shits and giggles, they provide actual functionality and not using them is a waste of resources. Linux having the desktop equivalent of ADHD is an example to avoid, not to mimic.

I feel the opposite. Cross-platform toolkits such as Qt are "good enough" but not great. I wish more apps would be written using the native toolkit of the platform.

What, so now I’m a developer who has an idea for an app and I must develop it for macOS, all the flavours of Unix, Windows, Android, iOS, and the web?
