IANAL, but these claims can't last. To the extent those projects are using WhatsApp's trademarks or copyrighted logos, they can stop infringing by renaming and removing the logos. There might be a "hacking" claim against users who use that software to access WhatsApp's servers, but not copyright (assuming WhatsApp doesn't claim copyright over messages sent through the aervice), of unknown validity, and probably not enforceable against a site which merely hosts code to do so. I think.
