Nah. Every claim he made is demonstrably incorrect, with the exception of his initial point that '"Sense of the Senate" language is often important in judicial and / or executive interpretation.' This claim is also incorrect, strictly speaking, but if we're charitable and substitute 'occasionally' for 'often', it at least adds something to the discussion. What it doesn't do is show Thomas to be wrong. "Sense of" resolutions aren't legally binding and rarely, if ever, impact public-facing policy. They do, on occasion, impact government-facing policy, for example SCOTUS recess appointments. The rest of his comments are blather and, while worthy of a good chuckle, are unworthy of response.

I know this because I have worked on those bills.

I do not know the legal or regulatory landscape around telecommunications in nearly such detail. But knowing the importance of such language in a REALLY significant corner, I would be very, very slow to regard any of it as without "impact [on] public facing policy." Not without a very thorough explanation of why exactly it was meaningless, and regarded as such generally throughout the industry.

Again, I don't know the industry. I do know that the making and implementation of law is a very complicated business, where the black and white readings of law do not yield the simple answers one might expect from logical analysis. And I know that in very important corners of government language like this, and still further from law than this, is effectively determinative of federal policy. So blanket claims that "sense of" language are without any real force are "demonstrably incorrect".
