Likewise from Brazil and likewise would rather see whatsapp gone from my devices. Sadly, I still need it for work and other official matters. Still, I'm slowly but surely abandoning whatsapp, by either convincing people I talk to to migrate to other, less anti-consumer services, migrating myself to sister groups or alternatives in other services, and/or abandoning a group or chat altogether. And all the while being vocal about it by raising my concerns about whatsapp (just saying "I don't like it and you should move too" can be pretty counter-intuitive with our countrymen). Hopefully, this way, I can drop it altogether once it becomes clearly irrelevant.
But this reminds me I haven't deleted/left any chats for a few days, so I'll take the opportunity to do just that.
