Do they? The metric includes "Unknown" and "Other" not referred to in this, representing another 5% of activity.

However, what the OP seems to be saying is that interpreting anything from the metric and trying to communicate that interpretation with others is pointless. Not even the linked article can decide whether Linux desktop penetration is 4% or 6%, and that's just one person. Good luck when you add a second person with their own feelings.
