It peaked at 4.05% in March. The last 2 months it went just below 4% as the Unknown category increased. For June the reverse happened, so 4.04% seems to be the real current share of Linux on Desktop as desktop clients were read properly/werent spoofed.
true, but in this case you can look at the same graph that was linked and see another Linux distro clearly marked that they choose not to treat as one in their headline. seems a little silly to me
