You could say that for everyone pushing for an encryption ban. If they use whatsapp, encryption, if they use https websites, encryption. Banning encryption is nigh impossible, it's like trying to ban prime numbers. What they'll actually do is get even easier backdoors and criminalise the masses that use it while still using it themselves.
They don't want to ban encryption, they want to block encrypted chat apps, precisely so they don't have to build backdoors. AFAIK it's not possible to break signal/WhatsApp encryption without access to the targeted device, and once you have access you can get the messages directly without having to break the encryption.
