[Koha] Use of Google Analytics and +1 on Koha website

Dear list, it came to my attention that the Koha website (http://www.koha-community.org/) includes code of Google Analytics and Google +1. I am wondering why a free and open source software community would use a corporation's spyware like Google Analytics on their users. More so as the site also includes code for Piwik analytics which runs locally on the Koha server afaics and seems to do the same things Google Analytics does, minus the "give all your data to an evil corporation"-part -- if you think analysing Koha users is neccessary. I would appreciate a discussion about the why and personally prefer these things to disappear so I am able to send people to the community website in good conscience. Have a nice weekend, Mirko
