This is kinda amazing that one has fight for it. I would like to think any museum should be immensely grateful to anyone willing to put in his time to either do the scanning himself or at least to provide an open platform to distribute the scans.
Honestly, I am less sympathetic about this particular case (I mean, who cares about accurate representations of Rodin's sculptures anyway?), but making an open catalog of all digital copies of all ancient stuff found this far really should be #1 priority for history as a research discipline at this point, IMO. It is absurd that anyone would actively prevent that. Yet, at some sites you aren't even allowed to take a photo (yes, w/o a flash), even if it is accessible. Most important sites and archives, obviously, aren't accessible to normal people at all.
