I yelled pretty loudly when Fedora first packaged libvpx because
fedora took a _known vulnerable_ version which Mozilla and opera were
patching around but where the upstream hadn't yet merged the fixes.

Things are more mature now but there are still somewhat scary fixes
happening, at least with the platform dependant code:

Mozilla being a vector for the widescale exploitation would be
terrible for their image— and also terrible for Fedora's, we really
don't want to create our own version of the debian openssl rng bug.
There really is a common interest here and the folks on the Mozilla
side are better informed about the risks.

The patches mozilla is carrying are visible as files in the respective
directories here:

I'd suggest that fedora folks interested in the bundling help by
making sure that the applicable fixes make it upstream. Even if Fedora
were to ditch the trademarks you couldn't escape doing this work.
