while i see where you’re coming from, being able to message WhatsApp users from a client app that respects privacy would be better than being forced to have WhatsApp installed on your device, with it snooping casually on your everyday device usage and your contact list and so on.
WhatsApp is the only Facebook app on my phone and i’d love to get rid of it without losing the ability to message all those buffons using it (which make up for 99% of my social circle)
