So I’ve always counted unknown as linux because who else would care / know how to hide their os ao that would put Linux at what %20?
The “Other” category is quite likely the many lesser-known OSes…
UNIX, FreeBSD, React, GNU Hurd and TempleOS to name a few…
I wonder how many fall into “Unknown”
It is certainly true that TempleOS won’t be identifying with one of the common browser user agents when surfing the internet.
Do we know if the steam deck counts an Linux, unknown or other?
