Brazil already arrested a Facebook executive and detained them for 24hrs this year over the fact they said there is nothing that can do regarding the information request.
I'm not sure what you're proposing Facebook to do here? Hand over useless encrypted data? Hold a cryptography seminar for Brazillian law enforcement to explain what end-to-end encryption means? Have more of their employees risk arrest?
They should say it like it is, and FB having a high visibility platform is a plus. Just put a banner there saying those guys are idiots in an authoritarian power trip, and fuck them. After that you'll probably be found dead or something. So YMMV
