@mcc Linux users are immersed in a culture that explicitly views software as a communal effort, working towards common purpose. Maybe that idea isn't explicit for everyone, but when people are steeped in it, of course they contribute bug reports! A bug report is an attempt to help the project! It may also feel like a complaint, but the material effect of it is helpful.
@irenes @mcc brushing the oxidation off my Bugzilla search skils confirms that Linux is responsible for disproportionately more bug reports to the size of the user base as a whole.
Windows is 85% of Firefox users on desktop, see https://data.firefox.com/dashboard/hardware.
I can write this up as a blog post if folks are interested.
