result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
