Earlier quoted context omitted.
> the abuse of "terrrorism"...abuses of power The federal court opinion [1], which rules in favor of Malamud's NGO, does not once mention "terrorism". The case is a copyright one. (And an important one at that.) I'm guessing the quote was from the lawyers' remarks, not the actual charges. So serious faux pas more than abuse of power.

You're conflating "accused of" and "charged with". Note that the title does not say "charged with".
We don't have any context beyond a Georgia lawyer saying "strategy of terrorism." Given how broadly that term is used nowadays, sort of like "war on X", this could have been a reference to Public.Resource.Org's legal or PR strategy or many other things.
It's a terrible choice of words, particularly for a government lawyer. But I don't see the evidence in the text to support the headline that he was accused, formally or informally, of terrorism. (Nor that he believed he was fighting terrorism, versus copyright, accusations or charges.)
TL; DR A lawyer using the term "terrorism" loosely is not the most interesting facet of this case.
