SO is for questions not "technical reports".

Welcome to the internet.

In general the internet does not have any ways of flagging
obsolete or copyright infringing content.

SO as one of the few places on the internet actually have a way
to do that. You can add a new comment explaining the problem.

That is core SO functionality.

You may not be aware. But the top lawyers and top judges in the US often
discuss what is copyright infringement and what is not in court.

So you believing that you can make an authoritative determination
shows a serious lack of understanding of the complexity of the
problem.
