This entire debacle also hurts the entire open source community. Look, if you think there's a trademark violation then sue them for it by all means (but since they let this go for so many years the outcome of this likely will be cancellation of the trademark) but the rest? just don't.
Edit: by "the entire debacle" I meant not this specific even but how WP Engine claimed Mullenweg demanded money, slandered them , all that.
