Re: Stop using Facebook and WhatsApp...
Copyright is removed because AFAIK FB TOS says uploading the image you "lose" copyright (or something alike), and you're liable, not FB, if you upload someone else copyrighted images for which you have no right.
That's not how FB gets away with it. The reason it has not gotten itself into trouble yet is that §506 (the "Criminal offences" chapter) of US Copyright Law talks about interfering with copyright notices with fraudulent intent, which is nigh impossible to prove in court. If FB was using the images to sell something there could possibly be a case, but just showing them with stripped EXIF data is not enough to trigger the "intent" aspect, even though it potentially removes data of the original rights holder.
That said, given the "gimme" clause in FB TOS where they can do whatever they want with images submitted it's probably not a good idea to put valuable content on Facebook anyway :).
