> In almost every standards working group Google holds the most seats

Can you substantiate this?

> It'd be naive to say that those in the groups are working only and only for the common good and don't pursue their employer's interests

This may be partly true without backing up what you were saying. You were saying something much stronger, which is that Google is deliberately holding back the internet. Now you're saying, "Well they aren't only working for the common good" which is just insinuation. Making the internet work better helps Google, which is why they do all sorts of things, from making Web browsers, to open sourcing codecs, to laying undersea cables. That doesn't imply anything negative.

Not to say there isn't anything negative. Just that your points don't seem to back that at all.
