Yes. In many circumstances, many people want varying, controllable degrees of orthogonality between their social, and professional, communications and relationships. "seen on HH:MM" and the like become dark patterns -- pushing us to serve the platform, rather than the platform to serve us. (A somewhat similar circumstance, with much debate and several perspectives, on the "true names" controversy of some years ago. "What" versus "who". Spam control. Content versus appearance. Personal versus professional. Public versus private. "True name" policies turned a lot of this from "opt in" to "opt out", or no choice whatsoever. Social media went from being something under the user's control with respect to their own participation, to a thorn in many users' sides.)
