I do agree that there should be a healthy debate, but i do take issue with saying things that are flat out wrong. One of macs os‘ greatest strengths is being a great developer machine - just look at how many people are using macs for data science, medical research, programming for cloud with AWS and Azure, web applications, middleware, backend and of course making Mac OS and iOS applications. Make it locked down will kill most of that in an instant.Why does someone have to have an "agenda" to theorise whether or not Apple will change course on macOS (or anything for that matter)? If @maflynn hated Apple so much, I don't think he'd be a Mod on MacRumors.
Look, I've been an Apple customer for over 25 years and I've been burned by them many, many times. Switching from PowerPC to Intel (when I'd just bought a G5 Mac Pro), killing off Aperture, gutting the iWork suite, the appalling butterfly keyboards, iPad "touch disease". Those are just ones that spring to mind.
Despite that, I'm still a customer as they make better products than the competition for the most part IMO. That doesn't mean I can't question their business practices or future intentions without having an "agenda". It's part of healthy debate. Criticism can be constructive and doesn't mean you "hate Apple" - and if you did, so what? They're an enormous multinational whose only concerns are shareholder profit and self-preservation. Their practices and intent deserve to be scrutinised by their very nature as a profit-making company.
Without a great developer community, the Mac will go into a downward spiral IMO. It won’t be any better than iPadOS.
