Stallman’s attempt to rename Linux
There was never any "attempt to rename Linux." Stallman simply wants to clarify which part of the operating system is "Linux" (the kernel) and which part(s) are not (many of which are his work, which Linux fans insist on also calling "Linux" even though the GNU project predates it by almost a decade).
Any "confusion" on this point is the result of Linux fans spreading mistruths (I assume only sometimes intentionally). Unfortunately at this point the myths are so firmly ingrained we have myths about the myths (like "Stallman wants to rename Linux") and in my mind Stallman is definitely fighting a losing battle nowadays. Still, a falsehood being widely accepted does not make it true.
