If you consider Steam spyware I have an attic full of tinfoil hats I've love to sell you.
Steam is no more spyware than Google Apps or Amazon.com is. To the people threatened by the idea of companies having your data...
People are increasingly becoming privacy conscious, hence the resistance to Steam, Origin, Google etc. You paint Google Apps, and assumingly Google products in general as non invasive/harmless, but they are not. I think since services like Gmail, Google, Google Earth etc. are ubiquitious you assume they are harmless. Also it seems that the privacy conscious are labelled by people like you as paronoid schizophrenic if they question or are concerned about seedy data gathering tactics. A bit extreme.
privacy isnt the concern of a soley fringe element consider these two, of many articles about Google:
Google Reaches Privacy Settlement with FTCMarch 30 2011 ABC News.com
"Google has agreed to adopt a comprehensive privacy program to settle federal charges that it deceived users and violated its own privacy policy when it launched a social networking service called Buzz last year."
Group Urges FTC Action on Google PrivacyFebruary 9 2012 ABC News.com
"Rep. Joe Barton, R-Texas, said he was disturbed by the executives' answers to questions about users' inability to delete data from sensitive e-mails or data that reveals visits to certain websites"
"Instead of the consumer being the master of the Internet, Google is the master of the consumer" Barton
I think Steam has a relatively decent privacy policy, but to equate Steam and Google as the same is errant.
