Users who want private comms with encryption and metadata cleansing can use decentralized blockchain based services such as xx Network's xxMessenger. xxMessenger can be blocked by the ISPs by blocking outgoing connections to xx gateways, but desktop-only Speakeasy Tech can use Tor Network (Tor Browser's Socks5 proxy or Arti) so it's likely to work better when telcos and ISPs are ordered to block connections or DNS lookups. There are other, similar networks, I just don't know enough about them to make specific recommendations.
