I think so, too. Although there is some intelligent people left (just start a programming related thread) that have interesting knowledge, other than that it's just low iq discussion if you even want to call it like that.
/b seems to be inhabitated bei Dieter and Karl-Heinz that somehow found their way from Facebook. They are IQ89 and probably like it on KhC because they don't can't get into legal trouble by what they post. They also don't understand English and the "Besatzersprech!" meme started to become code for "I can't read or speak English, stop doing it!"
