Don’t run it on a raspberry pi, run it on the same computer you use to access the Google search you are happy to call “free”.

Edit: Actually yes, both this and the healthcare need to be free - otherwise you’re grossly misunderstanding one of the key parts of the mission of open source. I pay for this so that whoever can’t afford it can access for exactly zero. Same for the healthcare - you might say it’s “not free” and everyone should contribute but what to you or me is nothing, could mean that grandma doesn’t get to eat. So yeah, free access needs to be a possibility. That’s the mission. I contribute to open source software and donate where I can so others who don’t have the knowledge or money can access it for free. There can’t be a price.
