I used Mandriva in the past,...and quite liked it. But I haven't used it in awhile now,..so I can't really give any kind of a complete picture. But what I've been able to kind of see,...is that it is the ones who have bought "subscriptions" over the years for the Mandriva "PowerPack" that are speaking of "demise". It seems that they might very well be left without being able to get any kind of a refund (if they pre-paid). Also,..many of the main Mandriva devs have already left,..and some are in the group to start the new "fork" of "Mageia Linux" (a community-based linux derived from Mandriva,..or continuing Mandriva). Mandriva,...meanwhile,..has had to skip a release,...and seems to have a lot of new (if not mostly new) devs to start the next release. That's as far as my knowledge of the "inner-workings" go. I'm sure there are others who know far more about this than I do. It isn't going to be the same,...at least that seems to be certain.
EDIT: I forgot to mention that the company (Mandriva SA) has been sold (it seems) to a Russian company recently.
The company was alway notorious for NOT communicating with the users,......so I only got what tiny little bit of
info that I have from their forum members,....(and trying to "google-translate" pages of French news on the web).
So any and all news,....may or may NOT be factual. (LOL!)
