Pivotal Labs is/was all Macs and has been "pivotal" in the pair programming era.

Building apps is hard, period. Many thousands of hours go into making commercial products. Many thousands of hours go into learning how to do so. It isn't something you just stumble upon over night.

Tone the language down a bit ("stupid fanboy"), it is unnecessary and doesn't work to convey your point at all.

> it's really not like it's hard to build cross-platform apps nowadays

An app that shares screens and mouse pointers with simultaneous audio/video transmission is not the same kind of cross-platform undertaking as a to-do app.

The entire point of this app is to share control of someone's computer, as well as drawing on their screens, having another cursor and this sort of stuff. It's a textbook example of an app that _would_ be very hard to build cross-platform.

Build a native app and you get complaints about cross platform. Build an electron (or other cross platform toolkit) app and you get complaints about resource usage and non native ui.

Seems to me that they know their target market (large tech shops with lots of devs on macos) and preferred to optimize for resource usage and user experience by going native. For another company, this could very well be the wrong choice, but they should look at the numbers and decide what makes sense for them.

There’s a whole thriving ecosystem of paid apps for MacOS, most of which are native and have a look and feel that can’t be done cross platform without compromises.
