that's incorrect. WhatsApp is end to end encrypted using the signal technology as confirmed by moxie. are you suggesting Facebook tricked the signal team into believing that WhatsApp is using end to end encryption when it isn't? a source: https://signal.org/blog/there-is-no-whatsapp-backdoor/

Honest question, then: outside of things like ethical concerns about supporting Facebook, and some missing features like enabling a passphrase to open the app, why should anyone use Signal over WhatsApp? Given that WhatsApp has a better UI/UX and that the people you want to talk to are much more likely to have it, and it supports some things that Signal is known for like disappearing messages (though limited to 7 day expiry).

I love Signal and all the work Moxie and his team have put into it and the protocol, so this isn't a diss to them, but just wondering what the disadvantages would be for someone just looking for an E2EE communication app.

One difference I suppose would be that Facebook would have all the message metadata; just not the contents.
