Hi Andra,
I agree this is misconception that a copyright license make any direct
change to data reliability. But attribution requirement does somewhat
indirectly have an impact on it, as it legally enforce traceability.
That is I strongly disagree with the following assertion: "a license
that requires BY sucks so hard for data [because] attribution
requirements grow very quickly". To my mind it is equivalent to say that
we will throw away traceability because it is subjectively judged too
large a burden, without providing any start of evidence that it indeed
can't be managed, at least with Wikimedia current ressources.
Now, I don't say traceability is the sole factor one should take into
account in data reliability, but certainly it is one of them. Maybe we
should first come with clear criteria to put in a equation that enable
to calculate reliability of information. Since it's in the core goals of
the Wikimedia strategy, it would certainly worth the effort to establish
clear metrics about reliability of information the movement is spreading.
Cheers

I agree with Maarten and to add to that. It is a huge misconception
that CC0 makes data unreliable. It is only a legal statement about
copyright, nothing more, nothing less. Statements without proper
references and qualifiers make data unreliable, but Wikidata has a
decent mechanism to capture that needed provenance.

Regarding attribution, commonly it is assumed that you
have to respect it transitively. That is one of the
reasons a license that requires BY sucks so hard for data:
unlike with text, the attribution requirements grow very
quickly. It is the same as with modified images and
collages: it is not sufficient to attribute the last
author, but all contributors have to be attributed.
If we want our data to be trustable, then we need
traceability. That is reporting this chain of sources as
extensively as possible, whatever the license require or not
as attribution. CC-0 allow to break this traceability, which
make an aweful license to whoever is concerned with obtaining
reliable data.
A license is not the way to achieve this. We have references for that.
This is why I think that whoever wants to be part of a
large federation of data on the web, should publish under CC0.
As long as one aim at making a federation of untrustable data
banks, that's perfect. ;)
So I see you started forum shopping (trying to get the Wikimedia-l
people in) and making contentious trying to be funny remarks.
That's usually a good indication a thread is going nowhere.
No, Wikidata is not going to change the CC0. You seem to be the
only person wanting that and trying to discredit Wikidata will not
help you in your crusade. I suggest the people who are still
interested in this to go to

<https://phabricator.wikimedia.org/T193728> and make useful
comments over there.
