They are providing your data to a third party who intend to use it for profit without your explicit consent. How heinous you view this act depends on how much you value your data, I suppose, but I think the analogy quite accurately describes Stallman's feelings on the matter and is thus an apt analogy for him to use in an article. It may not represent your feelings on the matter. It would be more productive to dispute why you think Canonical's actions are not a breach of privacy or not offensive to you rather than taking exception to his analogy.
