WhatsApp has clarified this move and even delayed the implementation but in the end pushed a Terms of Service that limited features for users who did not accept the changes. With this move, a number of people were annoyed and some even opted to using other chat services.
To counter this, WhatsApp is making some changes to these terms according to WABetaInfo. With the changes, the messaging app will make it optional except when messaging businesses that use cloud providers. For these cases, users will have to accept those terms before they can even send that message to the “special” business.
