I consider Sarah Mei an untrustworthy source. Last year she said the term Domain Driven Development is exclusionary to women because 'DDD' is a bra size in America and therefore the name must be a pornographic reference[0]. Furthermore, in the linked tweet she doesn't actually say anything concrete about Stallman, it's just her feelings about him. She's just stirring the pot.
