For 40 years this guy has been talking about the perils of proprietary software and people gave a shit to him.
Today people not only strongly defend proprietary software, but they think he is a moron, and even free/libre software activists think proprietary firmwares are okay as long their hardware works as expected.
Of course this is okay until their hardware stops to work as intended and you are locked out because the proprietary firmware, which usually is what happens.
