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.
I unspoofed Librewolf back to Firefox + Linux. That way I'm not contributing to Chrome and Windows market share and perceived dominance. Plus the more people don't spoof, the less of a need there will be to actually spoof at all as the Linux market share increases.
