The article you link is from 2010, granted it is ridiculous and does show how ridiculous PV is.

Still, would it be not wise to judge a book by it's contents than it's cover?

This particular person, Zachary Vorhies, is telling the truth, and the documents are correct could shed some light on the internal workings at google and potentially how they misinformed the public.

He was making according to his own testimony, $250,000+ (including the stock options). What would cause someone to just leave that and turn against the company?

I take anything from PV with a grain of salt, however to instantly dismiss something without actually looking at the contents is not very wise.
