Yes, but remember that Cyrillic is a script in decline. The 150,000 or so Moldovans in Transnistria are made to use Cyrillic, and they would prefer to use Latin, as can be seen by the crisis provoked by the decision to remove state funding from Latin-script schools. OK, none of these are reasons against the existence of a Moldovan Wikipedia in Cyrillic per se, but I think your point of this being able to be used for any tangible positive purpose is overstated. This can be seen by the fact that there are no contributors who are interested in adding information to the project at the moment (i.e. native speakers). Even *this* wouldn't be a problem.
As I've noted many times before, Latin alphabet is still taught in private schools in Transnistria. Nobody is being forced to use Cyrillic.
The biggest problem that people don't agree with, however, is that the Moldovan Wikipedia is biscriptal, and in practice is Cyrillic-only (article-wise), when Cyrillic is neither the majority script, nor an official script, while also ideologically representing a symbol of past repression (we can't always look at things in a political vacuum).
No -- what it seems to me is that most people either don't like the fact that Cyrillic is used *at all*, or that the name "Moldovan" is used. Nobody seems to have any of those nuanced feelings you detail.
