i've worked in two different large tech companies

when i give my hot takes pseudonymously on social media these phrases would be nothing but a LARP

i don't put my real name here nor do i put my professional commitments in my profile, and neither does this guy

Exactly. There is no scenario where we should expect some random anon to be speaking for Google. When that is the case a disclaimer is warranted, not the common case of speaking for oneself. He can write it once in his profile if he's so worried about it, not every other comment like he does. It's just inflated self importance
