Everyone respects other opinions here, this is the least expected in a civil discussion. Was there any doubt about it at some point ? :)
I know what van means. It's a different case, you can shorten to v. in dutch, search Robin v. Persie. It's a correct spelling of the name. It's different from De, Ben etc...
The perfect solution should know all these subtleties. It's difficult because BB deals with names from all around the world.
Aside from opinions, I still don't understand why you factually think it's better. You want to see the surname fully when possible ? My C. Ben Abdel Aziz has become C. B.A. Aziz, you see less of the name. That's what I am trying to say, I understand what bothers you but the chosen solution corrects it in some cases and creates it in others. Only now, on top of it, it cuts full names.
For the record, I have two first names and two last names, one of my last names is composed so that makes 5 words. I don't fit in the viewer :'(
I think the jury can take me as an expert on the matter :p
