Privacy is Priceless, but Signal is Expensive
Privacy is Priceless, but Signal is Expensive
Signal is the world’s most widely used truly private messaging app, and our cryptographic technologies provide extra layers of privacy beyond the Signal app itself. Since launching in 2013, the Signal Protocol—our end-to-end encryption technology—has become the de facto standard for private commu...
We estimate that by 2025, Signal will require approximately $50 million dollars a year to operate—and this is very lean compared to other popular messaging apps that don’t respect your privacy.

Would be interesting to see how this compares to XMPP or Matrix. Obviously the development costs something for each of those, but the hosting costs are spread out across each of those hosting an instance.
Yup, that's a big reason why centralized protocols aren't sustainable. XMPP is 25 years old (which is older than almost anything else on the contemporary internet) and thriving. Unfortunately, judging by the cycle of messengers coming and dying, and people still being eagerly part of that, this isn't something that people value very much.

Forgive the ignorance but does xmpp have the same features as signal, particularly around e2e encryption?
It's possible to implement XMPP with E2E encryption, there are at least 2 ways to do it.
But of course it only works if both users use a client and server that support it.
Worth mentioning that most modern clients support omemo at this stage.
