FWIW... i've been in Richard's presence several times when he was asked how to pronounce it by various people and he's invariably answered, "pronounce it however you like!" (i belong to the ess-queue-lite school of thought.)
I love when projects have cute puns in the name. I always am sure to correct people so they don't miss out on the fun. Luckily most developers are pedantic and like language enough that they don't get too annoyed with me. Same thing applies to PostgreSQL, it drives me nuts that sqlalchemy is not sqlchemy.
completely off topic at this point, but Jim Cornette reading paid advertisements for codecademy was very funny during the pandemic. He insisted on pronouncing it code-cademy while his co-host tried to correct him.
