So arguing "what if I spy on YOU?" wont convince anyone. They see that as a completely different thing.
Of course this only helps as long as your device isn't backdoored but that is true for any app.
(I say this as someone who regularly defend Telegram here, because in my opinion I don't have to pick one or another.)
I wonder what the next Crypto AG (CIA front) will be
NSA: VPN and "secure" webmail providers
CIA: They don't need fronts anymore, they have CISCO, Juniper, Netgear, etc.
so yeah if SV firms were not extensions of the US govt. (hardware firms too, not just software), they would have already been broken up years ago.
the senate hearings are just a charade used to stroke the ego's of the 'visionary' SV tech bro CEOs. they also show us how tech illiterate the working class has been made. [2]

The only semi-popular better option I can think of is Matrix, but getting people on Signal is already hard enough and using Matrix on a mobile device is (last I checked) far from ideal.
Security is a gradient, not an all-or-nothing. Signal is vastly better than almost every other electronic communication method.
- side-load a peer reviewed apk so you can check the sigs and make sure all crypto is being done locally (and to make sure that the implementation is solid)
- manage your own keys like you would with traditional pgp emails. Give your public to your friend. Force them to send anything sensitive using it. Maybe change to symmetric keys from asym but rotate occasionally. But you still have to trust the app you use to do this unless you want to do it manually each time.
*These don't necessarily solve the Metadata issue
Signal has open sourced clients with reproducible builds (on Android) and their encryption library has been reviewed by multiple 3rd parties to great acclaim.
PGP lacks forward secrecy, meaning if a key does get compromised all of your past correspondence is now also compromised.
Edit: As someone that has heard of forward secrecy but not how it relates to pgp, these were helpful reads:
I think this is the closest analogy I've heard yet, but not in windows on suburban, tree-lined street. People walk down those streets and the windows are at eye level. Someone could accidentally see into those windows. No, I think if we consider windows in hi-rise buildings in a major city, the analogy is getting much closer. Seeing into one of those windows requires a bare minimum of intent and possibly an inexpensive tool, say binoculars or a telescope. However I would be willing to bet that a large portion of hi-rise dwellers do NOT close their blinds on the theory of "No one is looking in MY window."
Next time someone says that ask if they use blinds in their house/apt, if you could setup a webcam in their living room, or if you could just read some texts between them and a significant other. Or ask for their passwords, date of birth, SSN, credit card numbers, pets' names, and parents' names.
Simple things like this are why I talk to people via Signal and why I'll never get a Ring/Nest doorbell, or any other 3rd party owned internet connected camera.
