More generally, Dave Winer seems to have an attitude of reflexively opposing everything that Google advocates, merely because it is Google that is advocating for it. It reminds me of the late 90's and early 2000's when open-source people talked about "M$" and reflexively opposed everything that Microsoft did merely because it was Microsoft that was doing it, leaving aside technical merits or other considerations.
Corporations are neither pure good, nor pure evil. They are collections of people with collective interests that they pursue. Sometimes, like in the case of HTTPS, or net neutrality, those interests align with our interests as developers and users. In those cases, we should ally ourselves with corporations and use their leverage to effect change more quickly. In other cases, such as with RSS, and vendor lock-in, our interests diverge and we should oppose them with all our might so that we don't lose the free and open Internet that we've become accustomed to.
In both cases, however, we should examine the issue on the merits of that issue, and neither support nor oppose merely because the "right" or "wrong" organization is pushing for it.
