We are a large and an absolutely legitimate publisher, that have been pestered and taunted by AdSense since 2009. Look at the history of this handle: it was created out of spite of the treatment we were given by the AdSense team.
If there was no strong bias of INNOCENT publishers against TAUNTING and making conducting our business difficult by semi-anonymous AdSense threats from no-reply email addresses, this story would be irrelevant and simply not resonate, regardless of whether it's accurate or not. Look the the Google adsense support forums where you used to redirect your clients, and at PeggyK that acted as an unofficial Google representative there, when people were banned with no explanation. Who is PeggyK- it was the largest farce I have personally witnessed, running a decent size business.
You guys created an entrenched persistent opposition by the arrogant actions of your AdSense policy team and its Ireland office specifically. For now, it's not important due to the disproportionality between Google and its clients and a near-monopoly of AdSense for eCPMS over $1, and GOOG is comfortable with this small risk.
