Not so much in countries where it's banned and the ban is enforced.
whatsapp is a private network, not federated and only works with a whatsapp owned client. to qualify i would have to be able to call someone on whatsapp with a generic VOIP client.
this is comparable to googles text messaging system that is built on xmpp. it used to be possible that i could use any xmpp client on any xmpp server to reach people on google. at that point google was xmpp. but when they removed public access it stopped being standard xmpp but became a custom fork of it.
