No, they don't. Technical feasibility to interoperate is only part of the picture. I clearly said above, that any participant should have an equal ability to interoperate legally. This includes no barriers to enter. License is like a visa to a country - it's a barrier to enter (which makes it not open).
If it's still not clear, license means "only those who can afford can use the encoder" and etc. Only those who can afford is a barrier to enter. I hope this is clear. Open codecs ensure equal accessibility and no barriers to enter. Encoders and decoders are available to everyone equally.
Pushing Apple and Co to support open technologies? It's only a natural thing to expect, since now they have a disproportionate grip as gatekeepers (in this context - it's about controlling codecs with patents). That was the whole point above, and that's exactly why Apple opposes it so strongly. It comes back to the same thing - control. You can call it an evil plot on their part, a basic instinct (desire for power) or whatever. But they clearly are allergic to the idea of the open Web, because it leaves them less leverage and makes it better for the people.

Google does a lot with enabling VPx support in hardware. It's more up to OS developers to support it in software now. Hardware (at least mobile SoCs) is shaping up well. With wider usage of WebRTC things will get even better, since WebRTC mandates open [free] codecs (here Apple and Co. didn't manage to sabotage it). The next big thing is Daala, which is next generation to both VP9 and H.265. That won't appear in hardware soon.
On the interoperability scale (it isn't a binary yes/no) MPEG4 almost certainly wins by the pure range of devices supporting it from blu-ray players, mobile devices, RaspPi etc.
It is you that want to control other organisations to bend them to your ideological position via the W3C.
If you want open codecs to become ubiquitous the next generation is where the fight is now. I don't know of an HEVC beater out there but if there isn't one getting into silicon roadmaps right now you may have lost the next generation already.
A royalty free codec would be nice but for me a ubiquitous one is better. That is a valid disagreement that we have but it shows how Apple (and others) opposition to standardising on codecs doesn't need to be seen as an evil plot but a difference in prioties between different "good" choices.
