They say they just want them to move servers to Iran, but any ones based in the USA would immediately land on the OFAC shit list if they did so. As such, they'll simply blanket ban all Iranian IPs at the deadline. Frankly, they'd already be *conditionally* banning any Iranian IP that comes accross if they didn't want to be hit with the USG's hammer. As far as whatsapp, they profess to log nothing, so it would be hard for em to know other than the NSA telling them about the traffic. Anyways, this essentially will ban any direct connections to these servers, further pushing Iranians onto using VPNs for everything.
