What's the business model of this and why I'm not allowed to use it without signing up?

The same thing with wrap[0], to have autocomplete, somehow giving special permissions in the OS is not enough to function; I also need to give my identity and communication details. It feels wrong to me.

Even if those weren't requirements, sensitive data is rather difficult to hide from your shell/terminal. Warp being closed source doesn't help either.

Edit: A nice alternative based on ZSH's native featureset: https://github.com/marlonrichert/zsh-autocomplete
