I don't even know who you think I'm dismissing. Mine is more of a generalized ennui directed at HN as a whole.
I don't think Google has actually done anything. The bar for experimenting with new code in Chromium is pretty low. This Chicken Little reaction to a non-starter is just a result of developing in the open.
Your post implies that anyone against this attestation is just going "Google terrible no good very bad evil", because Google "caring about real impressions" is what they said they wanted.
But you can "care" about something in good and bad ways, and the criticism is not "Google bad".
Now if Google cares about real impressions it's still terrible no good very bad evil.
