As others here have said, Linux distributions are well used by using official packages. That said, my two Linux laptops and Linux servers I spin up for personal projects are at least partially for the freedom to install anything I want.

For macOS, iPadOS, iOS for my watch, and iOS for my iPhone, I like the protected walled garden. I also like to sometimes use my Chromebook for the same reason: these closed platforms feel more secure to me.

I am happy that Apple OKed the HKMap.live app.
