Mistakes can be illegal. Intent only matters for small subset of laws.

If Google refused to fix it, it might be different. But I expect that, if someone were to file a suit, not even trying to get it fixed wouldn't be seen as acting in good faith.

Does every person who is impacted by this kind of thing have the responsibility to do Google's QC for them? What about people who never notice it? Maybe a lawsuit would be hopeless, but it sure would be nice to see some kind of real consequences here.

How do you even contact Google about an issue like this in the first place? My only communication with Google in the capacity of a user has been automated messages.

Meanwhile sending an email to Google asking for something to be fixed, could be seen as an act of insanity.
