They literally trotted out Hanlon’s razor as a moral argument that we should not blame Meta since it was probably just a whoopsie-doodle. This is a very common moral argument that people implicitly make or explicitly advance when using it.

I am pointing out how that is a absurd moral argument deriving from the rule of thumb. If anything, the corollary is the literal opposite.

Any stupidity indistinguishable from malice should be treated the same.

The usage as a epistemological rule of thumb just points out how great harm is usually caused by stupidity, intentional or otherwise, rather than intentional desire to cause the specific harm. If you aim to reduce great harms targeting just malice is not merely inadequate, it is likely missing the overwhelming majority.

One should try their best to make sense of reality before making moral arguments. That's what epistemological tools are for, like Hanlon's razor. Whether moral implications are downstream is unrelated to what the razor is, which you claimed to know but don't.

You seem to be claiming that intent is not related to justice or blame, which would result in an inhumanely cruel justice system where punishments don't fit crimes.

But don't worry, I attribute your proposal to stupidity not malice
