what on earth is this trying to imply? That google bleached the internet? Google got rid of the don't be evil tagline because it didn't fit with their corporate mission anymore, which was objectively more boring and more profit driven.

they're probably implying it was a sort of warrant canary or that they did not comply with overreaching government wiretap requests (the assumption being that now they do).

I find that to be a pretty charming belief. It's probably correlated timeline wise with when such things did change on that, but I highly doubt it was the reason for the mission statement change.
