The outcome in which the user has no control over the choice of the intermediaries, which is entirely under the control of the device maker, is not "one of many hypothetical outcomes" - it is how the current main deployment of the oblivious transport model works, and unless I miss something, there is no effort in sight to change this.

I think that there was a clear proposal in my message: don't just talk of doing things "for the end-users" but actually put end-users in control. The document should state very clearly that the net effect of these architectures on user privacy will be positive or negative depending on who is in control of the choice of where the traffic goes. Any protocol designs should make sure that users have a way to discover services and pick them for use within their applications. Indeed, this may also require regulation or antitrust enforcement for companies that will still try to use this as another self-preferencing mechanism, but the IAB should take a clear stance on how centralized it would like this kind of services to be.
