Sad, but not unexpected
At one point Mandrake, later renamed Mandriva (for trademark reasons) was a really good desktop distribution, perhaps the best if you liked KDE. I used it at home. But they had financial missteps and also managed to annoy their community with the for-pay Club whose benefits did not meet the expectations of many who signed up. I myself switched to OpenSUSE some years ago when it became clear Mandriva was going nowhere (tried also Mageia, but for whatever reason I could not get its early versions to work on my machine). But mostly I have good memories of the distribution. Some ideas and software from it still live on in others.
