We literally had better privacy when we had analog phone lines that anyone could tap into. That's just terrible.

FWIW I believe Riot/Matrix are planning e2e by default as soon as their implementation stabilises. Theirs is more complex/powerful than WhatsApp's though since they have multidevice support (which WhatsApp lacks). They've avoided making it default sofar due to bad UX and the possibility of losing access to conversations across devices, but it's improving rapidly.
* who's chatting with whom,
* via what means (text, audio, video),
* conversation time and duration,
* location of participants,
* how much data transferred etc.
There's a lot they can gather and imply from all that when WA users phone numbers will be known to FB, so they can graph connections via others' who run the FB app or previously shared their contact info. Also those who are perhaps logged in on, or simply visiting other sites they track via like/share buttons etc. Whilst what you say is encrypted, the circumstances around that conversation can be used, at least to advertise to you.
There is no way that an open IM platform will be able to guarantee E2E by default on all clients simply because someone/somewhere will produce a client that doesn't or doesn't do it properly. It is probably better to start with the E2E encryption system (in my example OMEMO) and then see where you can get it.
