FreeCharge from WhatsApp

So freecharge now allows u to send or request money from WhatsApp chat. There is a disclaimer that this has nothing to do with WhatsApp brand. Tried the feature out and my fear came true. They wanted explicit permission for accessibility to be given to Freecharge.

Based on which they'll now listen to ​ certain keywords​ u type in WhatsApp and a dialogue appears from Freecharge.

Not sure if I should be excited about the new feature or worried about privacy / potential malware threats.

Are those peoples phone numbers under the names in the pictures?
