They're US companies and I've heard that it requires intent according to US penal law. I find the article's claim that intent is established dubious. Since this is hard to prove without a whistleblower, it seems that they only have to fear civil lawsuits, and given that we speak of trillion+ USD companies they might feel confident to be able to fend these off or simply pay out the victims in settlements.

We speak of "potential" trillion dollar companies over indeterminate timelines.

While US penal law does not have the roman equivalent of culpability, you still have a mixture of liability/criminal negligence/recklessness, etc.

Given that we have had journalists prosecuted under criminal hacking statutes for discovering personal information in the rendered HTML of a web page, or publicly available attachments on a WordPress installation, I find the suggestion that intent is required to be dubious.
