Yes it is.

Alternatives beyond signal that normies can use: Email.

Spread the word!

Doesn't help when everyone just uses Gmail.

Convincing somebody who can hardly turn on their computer to get their own domain is just not practical. Even if they can get their own domain they still have to set up DNS. Good luck getting them to set up MX, spf and dkim.

I think things would be better if more people had their own domain. I just don't see any way of making it happen. I can't get my own family to leave gmail even with me handling all the domain stuff for them. Even my technical coworkers who are capable of this don't care.

Yep. Matrix is a decentralized alternative (provided you don't just use the default homeserver).

Yeah, but if you're going to use something centralised anyway, may as well use a more private option.

This issue isn't about privacy, it's about reliability. How reliable is Signal compared to WhatsApp?

Yes. In the ideal world messaging would've have followed the same federalized model as email. XMPP offers this, unfortunately few people use it or even are aware of it.

Correct. Switch to Briar.
