I'm sure trying to decide which snarky remark best conveys your condescending attitude towards a company's attempt to maintain its integrity and good standing is such a terrible dilemma.
If Google's integrity and good standing depends on not manipulating search results, there isn't a relevant case study for making such a determination - Google is still manipulating search results relative to Chrome.
Snark aside, I have to say that was my reaction - it's a more sincere apology than we usually get, and can be accepted as such.
