Pubkeys are also publicly available so it gives a way for nodes to communicate with eachother without knowing any other information. It can be very useful if you need to coordinate channel closures or notify peers of upcoming downtime for example.
Yes, pubkeys are public and used as identity within the LN protocol. But as soon as you start to use pubkeys in other protocols, you attach additional significance to them which can be used to deanonymize. Again, there is no technical reason to use LN pubkeys in a chat protocol.

There is no other protocol, Cipherchat just uses lightning. :)

Just because LN protocol allows users to doxx themselves, does not mean we should encourage it.

What doxxing? This is the same as running
lncli sendpayment directly from your node. Are you suggesting users should not have full control over their node to run whatever commands they choose?Keysend was introduced into lightning in the early days without issue because it turns out that it is very useful to be able to attach metadata when you are sending payments over the internet.
Most lightning apps support keysend in some way, if you have used a lightning wallet you have probably used keysend.
It sounds like you have an issue with the protocol itself. So your best course of action would be to open PRs in all of the major lightning implementations removing keysend support and try to get that merged. You will also want to reach out to as many lightning apps as possible to gather feedback about your proposed breaking changes.
I wish you the best of luck!
