Section 10 only seems to mention further restrictions as restrictions added by "you", so a licensee. Doesn't this reference to section 10 mean that section 7 explicitly limits itself to further restrictions added by licensees?
Section 10 seems to state that licensees cannot add further restrictions, without saying whether the original licensor may add further restrictions. Section 7 says licensees may remove further restrictions, and does not require licensees to determine the provenance of any further restrictions they encounter.
>All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10.
My reading of that is thay it is just referring to the definition of "further restrictions" in section 10, namely
> For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
