I hate the API changes... Keyword suggestions used to cost 20 API units for 300 keyword suggestions now it costs 300 API units for 300 suggestions without any stats with them and 1000 Units is $0.25... For SEO services it murders my margins and causes me to "pass the savings" on to my customers... Google's argument being... unless you're using the tool for SEO speculation you wont notice the price hike... well... that's every small business or larger out there... the costs will translate eventually into hosting, registrar, and bandwidth costs... We've already seen what online sales losses equate to in US store closures and job losses... It's entertaining when their plausible deniability campaigns shift to "We're smart, but not that smart. Those things are all coincidences. We just happened to short these companies and invest in those and our policies and knowledge of our own algorithms and procedures didn't influence those investment at all."
They never actually made that statement, but you and I know that a week after seeing their logs our stock portfolios would be changing and probably drastically. If the practice is legal then google should offer an investment fund managed within the web search team and analytics team. They'd corner that market too.
