I'm a long term linux veteran of almost 20 years. Cutting my teeth on Gentoo for at least 10 of those.
I've got to say, I'm surprised at the number of Apple haters on this site. Why are you here ?
Linux is great for what it is. There is nothing, absolutely nothing that Apple does that cannot be replicated on Linux; nothing !
The difference is in the user experience, and maintenance.
My Apple journey began in 2015, and got earnest since 2019 or thereabouts: so have no concrete experience with Apple/iOS/macOS before then.
Bit-by-bit, I was stunned by the ease of working in macOS: Apple pours resources into setting-up the system in such a way that you get straight to work. There's close to no friction between the idea you have in your head, and executing it in the OS/App. Then there's the integration with the other Apple devices via iCloud. Then you take the privacy considerations into account. All these things add-up to serve YOU ! With Linux, it's the other way around: you find yourself having to maintain config files, customising, filling-in bug reports, recompiling, rsyncing backups, maintaining mixed software versions. These things get in the way of your experience as a user, and deceptively sucks your time away from living your life.
An old MBP/iMac can still perform as a computer with Chrome/Linux etc, but only in essence. The experience would be totally different for the average macOS user. I certainly am never returning to Linux, not even to keep old hardware going, and that's saying something.
The guy who puts his money down for a brand new Rolls Royce, or even a Toyota for that matter, is buying a certain experience, reliability and support, than the person buying a discontinued model. Yes, he can still get support from a third party, but his expectations of experience, reliability and support are completely different. I certainly can't imagine a person who's moved to the Apple ecosystem from Linux, or where ever, be willing to install ChromeOS on his unsupported Apple device just so he can keep the hardware going; maybe if you only use third party apps that are OS agnostic: but then, why buy a new Apple device to begin with ?
To be sure, I'm glad Linux/BSD/Windows/Google etc are all there to keep everybody honest, but my-oh-my, Apple's doing a magnificent job.
MAGNIFICENT.
