The wiki does say to tag using ref=cam rather than name=cam (and gives an explicit example for an Amazon locker): https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dparcel_locker#Operating_options_/_Features

I suspect this is a refinement to the tagging guidelines since this locker was added. Changing the name=cam to ref=cam would have been much more preferable to just deleting name=cam and losing that data from the map entirely.

I’ve added the ref in https://www.openstreetmap.org/changeset/133488327, although it looks like that just conflicted, so another edit will be necessary to choose between name= and ref=.
