I'm not sure exactly what the correction that you're supposed to be issuing is. He cited the buddhists, not Buddha, and you say right away that "there's a huge gap between what Buddha saw and taught and what is said by the teachings in modern Buddhism." What is your objection, exactly?

That modern Buddhists don't have the correct teaching - so they are not right as stated. We shouldn't say that truth can change (as implied by the statement everything changes except change) as when truth changes it's not truth anymore.
