How in the hell do we not have a trivial "report a scam" option on phone calls and text messages? Which reports it to the FTC or FBI or something?
The only solution I can think of would be to get rid of all the SS7 to mapi gateways and force all cell phones to use internet based secure routing over RCS or preferably something better and also ensure that phones are not allowed to do spell check over the wireless carrier VPN. That would be a world wide project and requires cooperation from every nation. Either that or make specific countries walled gardens blocking all SS7 messaging and just accepting some things will break. I fully support breaking things that are already fundamentally broken. I would personally prefer direct phone to phone true E2EE taking the carriers, Apple and Google out of the picture even if there is some friction. It should be a physical phone-to-phone sync of sorts so you smack each others cell phones together, high five, do the hokey pokey and now you are E2EE with no layer 7 servers in the middle instead talking to a L4 VPN router that only knows how to connect one VPN to another over UDP. Everything else performed entirely by the phones using a different encryption cipher, hash, key, etc... Maybe using QUIC. For people that can't tap phones together maybe a fallback option for QR codes over video chat so you know you are syncing with someone you know, AI fakes excluded.
