MacOS feels like Android. It's more mobile OS than desktop/laptop. It's theoretically open but you can absolutely feel the walls closing in around you: only signed binaries are trusted by the OS (no asked who you trust), apps not from the app store are scrutinized heavily, etc.
Given Apple's recent actions in the US, MacOS doesn't feel like something I'd be switching to.
Just say the magic words: Mavericks forever!
And Apple's recent actions in the US are not of much concern anymore
