They know and they don't care: https://catala-lang.org/en/about

This programming language is named after Pierre Catala who is, together with Lucien Mehl, a pioneer of French legal informatics. Beware, the name Catala is typographically close to the name of the Catalan language written in Catalan : Català. However, the very narrow scope of our programming language should not be prone to set any confusion given the existing wide influence of the Catalan language and culture.
