Customer Copyright Notification fore Horrible Subs

Has anyone else gotten a Customer Copyright Notification fore HorribleSubs  Food Wars season 4 anime download ?

I know in fact that there is no us copyright fore new release  Fan sub translated anime.

It dos not say what company filed copyright claim  someone told me could have been crunchyroll. ,  Or some other  us company that only has the copyrights to their own sub and dubs of previous season of the anime  not season 4
