What about current owners?

Currently, it has a value only for those, who were affected by bugs. About “loyality” I have written above. You were loyal to Nik Software Inc. in San Diego, but they can’t give you an offer, because they do not exist. I do not think DxO has the capacity to evaluate, who was a real buyer before the collection went free. I do not expect people at DxO to look at millions of old invoices or emails to verify that you are “loyal” and ensure that you are the one who bought something by using your identity card screenshot and comparing the name on the invoice. And this all just to offer it for 20€ less?
