>Is it reasonable to say that ad blockers should not be blocking EventLogging (since it's just an internal logging system)?
Addblockers prevent requests to beacons, them being used for internal stats or otherwise (ad serving) so yes, it is pretty reasonable. A beacon does not necessarily imply it is used for adds [1]

I was just replying the same thing as Nuria, but I'll make a quick correction here: I think Nuria means it's reasonable for them to block EventLogging, not the opposite (which is what Ryan asked)
