That's fair, if your domain is erroneously put on the block list, Google should be liable for the consequences.

But my point is that any knock on effects like domain suspension, email deliver-ability, etc. stem from 3rd parties misusing the safe browsing list outside the scope of safe browsing.

I don't see how Google can be blamed for other companies erroneously treating the safe browsing list as a source of truth for generally malicious domains

That's fair and I agree. My opinion is that both should be liable in a case like this. If I had to attribute it, my starting point would be that Google is liable for the loss of website traffic and the registry is liable for the loss of email and all other lost services due to the domain suspension.

It spirals though because, like you pointed out, no one forced (ex:) Mozilla or Apple to adopt the blacklist. They did that voluntarily, so they should be responsible for their share. That's why nothing ever gets fixed. It's broken, but there's so much potential for finger pointing that no one gets pinned down and held responsible.

The answer is always the same IMO. Break up big tech companies into a million little pieces.

A lot of laws use the phrase "known, or should have known"

Google should not have known that someone would misuse their block list to block domains. But now that someone is misusing their block list to block domains, if someone brings it to their attention, the next time this happens, they will have known it.

I am not a lawyer, I am not your lawyer, and this is not legal advice.
