[Wikimedia-l] Is the capability to delete usernames compatible with the CCBYSA license?

2013-10-23 Thread Strainu
Hi,

Someone brought up an interesting issue: is it moral for the vandals
to be credited as contributors to articles (especially when exporting
the article as pdf)? After experimenting a little, it turns out that
deleting the usernames from the history removes them from the
contributor list.

While morality is a subjective matter, a more interesting question is:
is this behavior compatible with the CCBYSA license? Say we have
version A of a text, vandalised in version B and reverted in revision
C. Then version C is a work derived from version B, shouldn't it
credit the full author list of version B?

Going further, say that someone with an offensive username (or even
just an username unaccepted on wikipedia, such as a company name)
actually makes a valid edit, which is not reverted, but the name is
removed from the history. Is it fine to ignore the license just
because we find some usernames offensive? Shouldn't we instead credit
the user *at least* with a pseudonym?

Thanks,
   Strainu

Answer to the first question is very simple - C is derived from A, not
vandalized B revision.

Actually, following the same philosophy, one should wonder whether the
person reverting from version B to version C should be kept in the
contributor's list. At the end of the day, version C is an exact copy of
version A (i.e. no creative input of editor C), and version B is a
derivative version of version A, but versions C+1 and following are not
derivative versions of B, only of A and previous.

 just an username unaccepted on wikipedia, such as a company name)

I guess a pseudonym is the correct way to deal with this situation

No, the reverted text is derived from A, not from B. That there has been a
version in between at the same place does not matter. Same argument in
different wording: None of the creativity that goes into the vandalizing
from version A to version B is present in version C. Thus, version C does
not fall under the copyright of the vandal. Which means that there is also
no obligation to honor their licensing restrictions, only those of the
authors who are actually partly responsible for the final document.

Going further, say that someone with an offensive username (or even
 just an username unaccepted on wikipedia, such as a company name)

Is it usual to remove names from history without replacing them with
another pseudonym? I know of no such case.

 If we go this way, then none of the authors who added legitimate
 content in the past but had it deleted later should be credited. We
 would need a tool like git blame [1] to generate the author list.


Not necessary - need not be credited does not imply should not be
credited.

 Is this even possible? I only have the rights to do this on ro.wp and
 I see no option to replace the name with a pseudonym. I just select
 Delete the username or IP address and add a reason and the history
 shows the text username deleted crossed. And on the pdf export, I'm
 positive there is no pseudonym used.


I think changing the username has the desired effect, I am not 100% sure
though.

Indeed. It's just a feature request, and an ancient one:
