I question any "privacy" drafts authored by companies who's business consists of or is related to essentially violating the privacy of their users.

As you should! Luckily we don't have to rely on their salespeople or marketing, since we have a technical draft we can read and evaluate.

Not defending the mentioned companies here, but comments like these add no value. What specifically about the IETF draft advances the business of violating user privacy? Would it be better for users if Google, Fastly, Apple and Cloudflare abstained from standardization processes?

It could have legs without them, it just wouldn't have built-in clout that an appeal to authority affords.

Well, it needs browser support and server support... something like this needs adoption by major players before it's realistically useful in real world... Nothing to do with appeal to authority.
