I would imagine they will incorporate an opt-out mechanism once the service gets an official price tag.

And I would also guess it will happen eventually, but I haven't yet made a purchase through eBay which has had to go through the authentication process. I understand that the additional processing time is at least not unreasonable at this point. For over $250, most anything that I would buy is already going to be graded by PSA or SGC; I can't remember the last time I bought a raw card that expensive online. So hopefully most of those would be no-brainers in terms of going to the authenticators with a proper description.
