Jesus was all about becoming ungovernable. He said to stop using money and avoid storehouses so the tax man will have nothing to easily take. To let go of the temples and leaders so they cannot be used as tools of control. To use the laws of the oppressor against them
I don't think Jesus would be generally pro FOSS, because it's primarily funded by and taken advantage of by corporations. He was a revolutionary, he'd probably be going around helping people live outside the system
