If you do a small search, you will find some traces from 13/14 years ago, when Mageia tried to introduce such statistics. Due to lack of manpower, needed filtering of private informations, required change of the Mageia privacy policy and some more points, nothing happened.
As already mentioned, download statistics are kind of (useless) unprecise. They do not reflect if 100 systems where setup from 1 ISO, the ownload was partial, the download ISO was not used, robots and internet archives made a copy, ...you need to find other ways to meassure the usage.

That made me kind of chuckle.
I started my linux journey with the first Mandrake release, Mandriva and Mageia (up to MGA9). I followed the developement, did bugtracing, worked on the wiki and some more stuff. As long time users who knows from where Mageia came and how it evolved, how the internal works, what the buildsystem is, how the packaging process is, how many active contributers are there (and left over the past years), i can tell you that download statistics won't change anything.
I can't count the amount of reasons, which, after so many years, lead to my decission to no longer actively use MGA on my machines. I have only one physical machine left (from former several) where MGA9 is still installed (resides as secondary OS). I do not want to go to deep into details for my decission, but every other OS has overtaken MGA developement wise, maintenance wise, security wise, feature wise, and active developers wise. As example the exchange of the build hardware won't change anything on the antique building process and packager application process. All modern distributions are way ahead in the packaging process on modern build clusters and infastructures, and easy ways of getting a permanent or part time maintainer.
