Sorry, I'm going to be a stickler. The lawsuit says:
G52: Google expressly commits to: "disclose clearly [...] what types of [...] information we collect, if any, and the purpose for which the information [...] is used or shared with third parties."
G53: Despite this [...] obligation, Google does not clearly disclose in a manner easy for parents to understand what types of information is [...] used, nor does it accurately disclose that it takes certain rights to which it is contractually prohibited from doing.
we want to know the extent of Google's data mining and marketing of student information to third parties
The article says:
the state believes Google has been collecting and selling information [...] to third parties
The lawsuit says: Google does not disclose what it does, and does "certain things" it's not allowed to, leaving it unspecified. It does not claim explicitly that Google is selling or even sharing the data to third parties. Hood says: we want to know how much Google is marketing to third parties; he does not explicitly state that Google is doing so. He also uses "marketing" rather than "selling", and I'm not sure that this means the same. The Reg article says: Google is claimed to sell the data.
The confusion between the first two might be on purpose from Hood in front of the press, but what the article claims is yet another thing.
