They are specifically heuristic algorithm based and by definition they aren't perfect but can actually keep up with the massive volumes and unknowns. It is /not/ random or capriciously applied even if outcomes are flawed which makes the comparison apples to hand grenades regardless of false positives.
Even if their approach utterly sucked it wouldn't be libel or defamation any more than saying "Never trust a company which changes its name without the old name featuring sonething which becane obsolete." or "Any company with a rate of growth over 10% for ten consecutive quarters is probably a Ponzi Schene".
Any time they make a statement about another entity which is demonstrably untrue and causes harm to somebody's reputation or prevents them from generating revenue, that is grounds for a defamation lawsuit. The fact that they have automated their defamation does not remove their culpability.
It might also be a violation of anti-trust law since Google has its own software-delivery channels which are not subject to the same warnings.

It's completely different because those statements are not made about specific entities, nor do they make specific accusations about any entities.
