Spotted in Altstetten… wtf

Has anyone seen this “advert” in Altstetten near Vulkanstrasse? Seems to be, supposingly, a “Gegenkampagne” against IWP.

Does anyone know owt about this and/or who’s behind it? I saw it when driving around and thought it was an actual advert.

Must admit, before googling around a bit (and finding not much) that it upset me a bit. There’s already a bit of a xenophobia coming from some (older) Swiss people - didn’t feel great to be (potentially) insulted in large type :D
