Some things are heavily optimized to promote their ecosystem, I agree. But it's Apple software so it's expected they want you to use their ecosystem. But they always provide an escape hatch. Yes random binaries are harder to run, but that's for the security of 90% of all mac users. The last 10% still have ways to run it anyway, it might be a few clicks more yes. Overall I think it's still a very developer friendly operating system when you compare it with the competition, Windows. Which is spamming you with ads, also many Windows Defender warnings, random binary removals or refusing to execute them even when you allow it.
