> Should Your Notes Be End-to-End Encrypted?

Yes. That's why I use Joplin (which is free and open source btw) and not some proprietary freemium app that to explains me that I don't necessary need E2E encryption for my notes.

Do you have something that allows you to publish that as well?

Use case - I want to keep some notes for myself e2e on my laptop & phone but every now and then I'd like to publish a few of them under a pseudonym anonymously on the internet.

Trilium Notes offers this: https://github.com/zadam/trilium/

Note: I run a paid 3rd-party synchronization service for Trilium Notes that would offer the publishing part of what you mentioned easily, without setting up a cloud server: https://trilium.cc/
