Genuine question - How hackable is this? Can I have the voice commands redirected to my backend server where I can process it as I please?

This is Home Assistant. Everything is hackable.

Inside Home Assistant the processing is delegated to integrations providing Speech-to-Text, command processing, Text-to-Speech. You can make custom integrations for all of them

It's fully open-source. I think the default use-case is to have the voice commands processed locally

Probably as much as any other smart speaker without having to give your data away.
