I know you and like you personally, that why I can say that this mail is
clearly not your best argument.
Despite saying multiple times this is not a manifesto nor against Wikidata,
your mail seems clearly fuelled with biases and misjudgements (especially
Wikidata can't be « discontinued quietly » not now that it's so widely used
in Wikimedia projects, even the wiktionaries are *already* using Wikidata).
Dissecting each single phrase point by point is violent, borderline mean
and definitely not constructive ; cross-posting this mail on multiple
places doesn't help either. This is not the good way to debate peacefully.
Some of your argument are good but most are quite poor and really missed
the big picture.
For better or worse, Wikidata choose CC0 and it will be quite difficult to
change the licence now (the example of licence change on OpenStreetMap
illustrate it quite painfully). We have to get approval of the community,
there was multiple lengthy and non-conclusive discussions, it's not
something that will be done with a ranting mail.
For me, the situation is quite simple, Wikidata needs lexiographical data
and the Wikimedia projects needs Wikidata to have these data. Nobody
suggest in no way to do license laundering nor to violates Wiktionaries
licence, in fact we could simply import Public Domain sources (in the same
way the wiktionaries did, in frwikt a big chunk of entries come from the
*Littré* and the *Dictionnaire de l’Académie française*, and there is
enough dictionaries waiting in the Wikisources to keep us busy for years)
but it would be a shame for Wikidata to not profits from wiktionarists
Let's get over the petty and unsolvable issues and work intelligently and
pragmatically to improve Wikidata.
You entitled to disagree with the way that has been chosen and not take
part in it (and from your editcount, I see that you don't) but please don't
destroy others efforts and try to be more aligned with the wiki-spirit.
