>I keep seeing folks float this as some admission of wrongdoing but it is not.
It absolutely is.
If they knew without a doubt their equipment (that they produce) doesn't eavesdrop, then why would they be concerned about "risk [...] and uncertainty of litigation"?
It is not. The belief that it does is just a comforting delusion people believe to avoid reality. Large companies often forgo fighting cases that will result in a Pyrrhic victory.
Also people already believe google (and every other company) eavesdrops on them, going to trail and winning the case people would not change that.
