This is true; but on reflection, it is beside the point.
The critical point is that there can be no act of communication -- no application of intent -- unless there is both a listener and speaker. So, if I talk to an empty room, I am talking but not communicating.
On the other hand, even when we are communicating, it does not mean that it is successful communication: I can listen to you, and still fail to understand/act what you are saying.
I agree that the speaker and listener are actively involved in communication. Our question is what is their involvement. When does listening include the activities that the speaker wishes to follow from not only the listening but hearing and understanding.
In the Action Model, the service identifies the messages it understands when it is a listener. It does not guarantee it will do anything for any other messages. It does not need a speaker present to still understand those messages.
So the disconnects are:
1. There seems to need more than a speaker and a listener to have a useful service interaction, i.e. the listener has to commit to initiated activity. Our discussion doesn't include that.
2. The speaker can apply intent without the listener receiving the message or responding. There is action on the part of the speaker but no interaction.
3. Action, or at least potential action, exists on the part of the listener without any speaker. There is potential for interaction, there are prescribed steps in interaction, but there is no interaction until until there is a speaker, an exchange of information, and an understanding of that exchange.

There is a book that I recommend that you read. It is called "Using
Language" by Herbert Clark. It is pretty informal but gives an
excellent account of the concepts involved in human communication, and
by extension computer communication.
Essentially, the bottom line is that both speaker and listener are
actively involved, and that the communication has not happened without
both participating. And he also addresses (not in the same language)
the counts-as relationship.
As for denial of service, etc., I agree that willingness is an
essential part of what is going on. hence the active role of both
parties!

appropriate to withhold/withdraw willingness, whatever has the
listener may not process the email if they suspect embedded malware.

No, this does not get the join action aspect.
I admit that I thought some about the Patient in a CA. I believe that
the Patient in a CA is the medium of communication. We jointly act on
the email medium when we communicate by email. It is a little tricky
because there is some danger of infinite regress:
I act on an email to compose it and to push it into the Internet. You
act on the email to open it and read it. But these actions are the
actions of Speaking and Listening respectively. The Joint CA is the
combination of the two. In that world, we are using the Internet
(actually SMTP) as a means of communicating and we act on it by
sending and receiving messages (the messages become the Instruments of
our CAs).
