That looks like it's coming from OhMyZSH, not ZSH itself.

https://github.com/ohmyzsh/ohmyzsh/blob/959b6cf5eed78f108dc6e0f46b53816f5168dd3a/tools/upgrade.sh#L265-L283

The message comes from the update check. It seems there is a setting somewhere to make it less verbose. Change verbosity from default to minimal.

Find out yourself how to change ohmyzsh settings please, I gotta go now

Using a shell that has social media, and closed source shit ones at that, would be enough reason for me to switch tbh

I have never seen this.

Consider using an alternative, like ohmyposh?

Is this message printed onto the screen everytime you open zsh?

It might be hardcoded into the config files, e.g. ~/.zshrc.

• I once thought zsh was slow.
• I thought it was slow due to Python
• Then I removed the Manjaro's OhMyZsh
• Turns out zsh was neither slow nor Python

Though OhMyZsh was slow because I had the system on an HDD
