You're probably right that it's paranoia, but I just don't see any promises from Google to shield from or take responsibility for infringement; they just suggest that they could license patents in the future.
It probably wouldn't stop me but I would only do so without any sort of expectations from Google.
None of the major codec players promise to shield from or take responsibility for infringement, at least not for normal licenses. Not MPEG-LA, not Microsoft, not IEEE, not Google, not Fraunhofer.
