It's not that Linux/BSD don't offer the most freedom (though as many have pointed out MacOS is essentially BSD with an Apple WM/GUI). It's the snobbishness of saying 'only ____ makes you a TWUE PWOGWAMMER'.
You can see this to some extent in other professions. Cardiologists and neurosurgeons get paid big bucks because their job is life or death stuff and requires skill and innovation. But would you want to work with a cardiologist that goes around sneering at every other kind of medical professional and saying they're not real doctors? Of course not, because they're assholes and when people like that screw up they'll blame their colleagues or patient rather than admit fault.
Back in the tech context, you can pursue authenticity into absurdity. You're not a real programmer unless you use (language). You're not a real programmer unless you contribute the language. You're not a real programmer unless you get into kernel hacking. Sure, you call yourself a programmer, but do you even assembler? Programming? Sorry, I design chips. Chips? Do you even basic circuit designs. Me, I roll my own capacitors built from carbon nanotubes...and so on up through materials science, physics, and mathematics.
