December 28, 2006 -- Mark Shuttleworth says "We know now that there are probably at least 8 million [Ubuntu] users."
October 17, 2007 -- Mark Shuttleworth says Ubuntu has "in excess of 6 million users."
I have a follow up question, Mr. Shuttleworth. How did you manage to lose about 2 million users in less than 10 months? What does that mean for the future of Canonical and the funding that you provide to Ubuntu? Or were your numbers then, and now, simply made up? How many users do you actually have? Your inconsistent tales to reporters detract from the good work that the Ubuntu community guys like Jono and others are doing.
At least Fedora makes a good-faith attempt at statistical transparency.
