> used to be skeptical of the government provenance

Do you mean skeptical on which government was responsible or that it was in fact a government effort?

I can see how attribution could be debatable (between two main suspects mainly), but are / were there any good arguments against this being a gov effort? I would find it highly unlikely that someone other than a gov could muster up so much domain knowledge, source pristine 0days and be so stealthy at the same time.
