Yes, the memo from Google makes it seem that, however they don't just come out and say it clearly... probably because they can't, or can't yet, confirm who leak

Yes, the memo from Google makes it seem that, however they don't just come out and say it clearly... probably because they can't, or can't yet, confirm who leaked what if anything. An interesting question for Google to answer would be how many Google employees have accessed/crawled all the internal data. Considering the sort of talent, curiosity, and technical skills that Google hires I would expect that the four fired workers are not unique in that regard.
