That power, today, is expressed through technology, and these overlords hold their control via proprietary software and anticompetitive business practices.

To seize power back, you need to relinquish their shackles by using technology that is designed with user freedom in mind, not "lock-in", and support businesses constituted of that ethos.

We don't need to support business. We need to support political institutions that oppose proprietary software and support people's right to general purpose computing

It's exactly this over reliance on companies to shape society that got us in this mess

Free as in freedom!
