You can go to any number of sites (here's a nice one https://webencrypt.org/openpgpjs/), and encrypt a message. You can exchange public keys over any text channel. You can then send encrypted messages over that text channel. Anyone who really needs to send encrypted messages, trivially can. Of course, many criminals won't, but should we all sacrifice our privacy for such a pathetic measure of security?

ChatControl proposes "on device" scanning, meaning before/after encryption, thereby making encryption useless.

You could still have an airgapped computer where you encrypt your messages with GnuPG or similar, and then send those.
