Freedom of speech exists to provide freedom of expression, even if it is controversial. I don't consider planning crimes, especially ones that would end freedom of expression as a societal value, to be covered under freedom of speech. Certainly each individual comment on Parler can't be considered to be planning a crime. That can't be said for the platform as a whole.
