As much as I love Firefox, the only thing I can read here is: We have failed to diversify, and we would really like our yearly $400 million to pay our CEO

Feels like the underlying issue is Mozilla's dependence on Google. I can understand why Mozilla took and don't want to give up the search deal - it gives significant funding for only a minor concession, so it's easy to justify as pragmatic/ends-justifying-the-means perspective ("this small compromise or no Firefox") - but here it puts them in an awkward position of needing to argue against attempts to break up Google's search monopoly.

Correction: Google's response to proposed remedies.

Mozilla is just the mouthpiece.
