"No big org is using pure OSS"

On the contrary every big org is using OSS.

OSS is in everything.

That there is 'nobody to sue' is besides the point, it's like suing the inventor of the fork because something happened with a fork.

If you bought something complicated from someone with a contract and you depend on it doing ABC and it doesn't, then there's a case of liability.

But tons of software is OSS and there's nobody to sue.

'Liability' in software is maybe important in some areas, but mostly it's not.
