The decision to not supply H.264 is ideological for sure, and I can understand that from the patent perspective, but then they have MP3 (patent-expired in 2017) but not MPEG-2/H.262 (patent-expired in 2018).
Also note that VP8/VP9 is still patented, but just licensed freely. IMHO that's less free than patent-expired (public ___domain).
My understanding was H264 is kind is licensed freely too after Cisco made their agreement usable for everyone ?
Firefox can support mp4 over h264 despite their clear FOSS aligned goals , I am surprised that Wikipedia whose goals more align to open information rather than open source directly has challenges .
