Google's achilles heel?
They don't seem to want to attract the attention of the regulators, preferring to drop a lucrative deal rather than argue it out.
Hmm, I wonder why - could they perchance not want folk asking questions about data retention, privacy, advertising rates, placement, etc, particularly legal folk, with a fairly large legal toolbox, and a lot of case law to ask Google to open their dirty laundry.
Hey-ho, knowledge is power, and knowing what scares google is always useful
