in short, the developers of dwm are reprehensible people who have publicly espoused hateful positions, alongside
doing things that just so happen to be nazi traditions (this also took place after white nationalists in America held one of these in a VERY high-profile manner), one of their lead developers
basically is invested in conspiracies about Jews, and their event organizer's
public email server was named after Hitler's first Eastern Front military headquarters (Poettering had a link regarding this in re harassment he receives from Suckless, but the link has since broken).
