@yianiris @fsf Linux was proprietary software in 1991, relicensed to the GPLv2-ambigious in 1992 and made proprietary software again in 1996 via the addition of the first proprietary program.

Linux was only fully source-available 1992-1995, before the concept of "open source" existed (1998), thus putting "FOSS" or "open source" anywhere near Linux is an error; https://opensource.org/osd (unless of course you regard "FOSS" to mean, gratis, partially source-available software).


Such restrictions are really expected from a group that composes of many proprietary software developers that either don't care about freedom, or actively work against it.
