No, we (the companies) don't.
We work to get web features that we can leverage.
If we can get away with them being adopted by everybody but solely controlled by us, it's all the merrier. If we can get away with keeping some features to ourselves as a competitive advantage ditto.
If we can push our agenda and standards instead of collaborating and iterating faster on common ones, that's great too.
We (the companies) could care less about the web, in any way in which it doesn't affect our bottom line.
In fact, if we have to stall the Web's progress to protect some of our own investments and offerings, we're all for it.
Also, if we have to stall the Web's progress just to avoid some competitor getting his stuff adopted and standardized first, we're all for it.
