Whatever the reason might have applied to Vorbis, it seems like would
also apply to VP8. I've also heard similar arguments about "nobody going
after Speex mainly because nobody with deep pockets is using it". That's
despite the fact that Speex is being shipped by companies like
Microsoft, Google, Apple and CISCO. You would have thought someone would
have sued if they had something. Similarly, Vorbis is also shipped by
(at least) Microsoft and Google and we haven't heard of anything. In
fact, the only codec related patent lawsuits/threats I'm aware of all
involve ITU/MPEG codecs with established patent pools around them. So if
anything, I'd say VP8 might be safer from unexpected risks than H.264
