An algorithm reading your email to look for words to server better ads is hardly spying imho. I rather see ads of things that interest me than ads for casinos. And I'm hardly a MS lover.
Unless, of course they are looking for the words "male", "escort", "date" in e-mails from a (most likely Republican) Senator, married with kids :-)

Any form of privacy invasion can be - and eventually will be - used for nefarious purposes.
