It has nothing to do with the stated cause, its all an effort to strongarm Facebook into censoring pro-Trump content in the run up to the presidential election. They already heavily censors pro-Trump content, even just simply pro-American content like flags and such, and have for years, but subversive assholes like Sacha Baron Cohen want to make sure to rig the election against Trump as sturdily as can be.
They all yell about democracy, yet have worked tirelessly to rig the elections so no democracy is possible.
