Well, if you read what the gentlemen from Adobe has said since, his objection on the private list was about how the chairs of whatever committee he raised his objections to basically made a unilateral decision without discussing the objections. So, at least according to him, the private list material is essentially objecting to the process by which his public objections were handled.
Yes, but since all objections are to be made in public, in order to foster transparency and documentation of the process, I have a hard time understanding why making private objections to those same individuals that he had publicly objected to before would help.
If the process is truly broken, get it out in the public and document it. This reeks of the type of politics that is meant to kill something through subversion of the process and delaying tactics. If you can't kill HTML5 outright, kill the process of developing the standard and you've effectively done the same thing.
