> But now Whatsapp retains access to all the photos I added unless I go into settings and revoke access to those photos. Creepy.

I think this is good enough. If you consider they do shady stuff with your pictures, you might as well consider that they hold on to anything they get their hands on right away.

I think you meant to say you don’t think this is good enough? And I’d second that.

No, I do think it's good enough.

My idea is that if WhatsApp can't be trusted, once it gets access to any file, it will hold on to it. So revoking access to something it already has won't accomplish all that much, since I've already figured that I can share that file with them.
