Just for context, the quoted manifesto was originally written in French (https://monoskop.org/images/3/3b/Dada_3_Dec_1918.pdf). In that version, that particular sentence is gender neutral: "tout le monde fait son art a sa façon".
I would say that that their updated quote is a more accurate translation of the original than the English translation they initially used.
