Indeed. Buried away invisibly in section 3.2 and 3.3 we find the following:

• We do not claim ownership in any "Content"
• but:
• you hereby grant to us an unrestricted, irrevocable, perpetual, non-exclusive, fully-paid and royalty-free, license (with the right to sublicense through unlimited levels of sublicensees) to use, copy, perform, display, create derivative works of, and distribute such Content in any and all media or distribution method (now known or later developed) throughout the world. Additionally, by posting any Content on the Services and making your Content available to others ("Third Parties") via RSS distribution, you hereby grant to all Third Parties an unrestricted, irrevocable, perpetual, non-exclusive, fully-paid and royalty-free, license (with the right to sublicense through unlimited levels of sublicensees) to copy, display, and distribute such Content in any and all media (now known or later developed) throughout the world. No compensation will be paid

In what way is this not claiming all the rights of ownership?
