I always wondered why do we need all this legal bullshit... and I never liked the order of the words in these sentences... If google has a button, that I press and my content becomes available to the whole world... it is me pressing the button. It should be the other way around... or at least say: you as a user have the option to make your content available, modify your content, distribute or bla, bla, bla using our services... and you give no license to the provider. ps: still... I don't care about these terms much, as they really appear everywhere. Although, I'd feel much better if using an online service, in legal terms would be closer to buying a tool in the hardware store. :)
