Was that the punch in the face, or was it all the morons intentionally misinterpreting this argument and saying "but why would u want to send nonsecure messages are you aware SMS isn't secure it's like so insecure to send SMS bro it's not secure it's like literally a security risk bro SMS isn't secure at all and also are you aware SMS security is poor"

Same here. It's pretty frustrating.

My family still uses it vs texting. We like the video calls as well. :)

Well, yes. But when all your friends are already on Facebook Messenger, good luck getting them to install Signal only to talk with you. Network effects are important; a messaging app has no use when you have nobody to message on the app. Supporting SMS was taking advantage of its network effect, and I don't think their network was big enough to be self-sustaining for most users (it wasn't in my case, my only contact in there is my wife).

Maybe, but if I want to privately talk to randos from the internet, then using my phone number like with Signal is a no-go from the start. Threema is paid and only partially open source.

Session is fully decentralised and while you can think of crypto whatever, at least it gives people the incentive to run nodes, unlike Tor where the incentives are all over the place, or centralised messengers which are fully reliant on one entity.

Try Matrix or XMPP.

Facebook Messenger offers optional end to end encryption just like Matrix. Just like Matrix, the server knows who you're talking to, what groups your in, who else is in those groups, how many messages you sent to which group, who's messages you react to, etc. But the actual text of the message is technically encrypted so Facebook can't respond to subpoenas for your messages. I use Facebook Messenger as an example because Facebook is (correctly) generally considered not private or safe.
