The Fine Print
So how do Facebook and Google+ stack up when it comes to their treatment of content ownership and user privacy? Facebook's Terms of Service are, regardless of their statements of intent, both brief and very wide in scope:
"For content that is covered by intellectual property rights, like photos and videos ("IP content"), you specifically give us the following permission, subject to your privacy and application settings: you grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook ("IP License")."
Google+, on the other hand, provides significantly more detail:
"You retain copyright and any other rights you already hold in Content which you submit, post or display on or through, the Services. By submitting, posting or displaying the content you give Google a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute any Content which you submit, post or display on or through, the Services. This license is for the sole purpose of enabling Google to display, distribute and promote the Services and may be revoked for certain Services as defined in the Additional Terms of those Services."
There are two key differences in the fine print: the first is that Google spells out that users retain copyright. Facebook makes no such promise. The licensing terms that Google refers to are also very broad in scope, but they go on to specify a series of details around how they can make use of content posted by users.
"You agree that this license includes a right for Google to make such Content available to other companies, organizations or individuals with whom Google has relationships for the provision of syndicated services, and to use such Content in connection with the provision of those services.
You understand that Google, in performing the required technical steps to provide the Services to our users, may (a) transmit or distribute your Content over various public networks and in various media; and (b) make such changes to your Content as are necessary to conform and adapt that Content to the technical requirements of connecting networks, devices, services or media. You agree that this license shall permit Google to take these actions."
