They are encouraging their users to post not just their own private info, but photos and info of 3rd parties.
They only exist to exploit people
They dishonestly track with the "like" buttons that web admins are pasting on their sites (that might be illegal. At least though El Reg has four Icons on mast head, they don't have the evil scripts provided by those companies.).
They profile people by ethnic background (so called "race"), age and gender orientation.
They constantly pester users to add more personal information. They allow lies, propaganda, marketing to be disseminated as news. They claim not to be publishers, but edit, curate and decide on useres reach even to their followers based on payment. They claim exemption from existing regulation because "tech" and only a "carrier". Both lies. Even phone numbers by having features only enabled by SMS code.
They should be shut down. They are poisonous to human culture, deceptive, and parasites on the Web.
They should not be permitted to run, own or fund any of their so called "free" filtered internet access programs.
