Is it possible that this bothers you personally? Flying really is one of the most negatively impactful things that an individual can do. Shifting the focus to government or business may be 'also correct', but you could also call it whataboutism.
Agreed, the metrics he uses for CO2 consumption via flying are misleading: he compares the flying against total average CO2 production per US Citizen per year. Clearly, he's doing more than just flying in his life, so the comparison is meaningless.
