That’s the best part. Remind them that it’s not about you. It’s about whistleblowers and journalists who need to protect their sources, and lawyers who need to communicate with their clients. That tends to bring the ego down a peg ;)

But honestly, it’s best not to be aggressive. Some people don’t care much, and you won’t convince them.

FWIW, all my non-technical friends use Signal with me, and they know about verifying safety numbers! It can be done.
