As someone who went from FOSS -> Apple -> FOSS, I fully understand the love people have for the Apple ecosystem. In terms of proprietary hardware and software, they have a sheen and an inter-operation between their products that is genuinely unmatched.
That said, what ultimately pushed me out and back to Good Ole FOSS™ was the lack of any control, and the lack of any transparency. The idea of trusting a for-profit company with anything beyond my email address and sometimes phone number is just something I dislike doing. Apple's processes are extremely opaque, and the last thing they want to give users is any control over their products, it's an antithesis of what I desire from digital electronics.
As for if non-technical people should look into FOSS. I think FOSS can really give people a fundamental baseline of digital computing, and in the modern world such a baseline is extremely valuable. If they decide afterwards they prefer their proprietary ecosystems, Apple or otherwise, that's their prerogative and there's absolutely nothing wrong with that.
Same here, everytime I ever saw reddit in my search results I'd audibly sigh. How they've managed to make their user experiences so extremely hostile is beyond me.
