We should have the ability to run any code we want on hardware we own

> In this context this would mean having the ability and documentation to build or install alternative operating systems on this hardware

It doesn't work. Everything from banks to Netflix and others are slowly edging out anything where they can't fully verify the chain of control to an entity they can have a legal or contractual relationship with. To be clear, this is fundamental, not incidental. You can't run your own operating system because it's not in Netflix's financial interest for you to do so. Or your banks, or your government. They all benefit from you not having control, so you can't.

This is why it's so important to defend the real principles here not just the technical artefacts of them. Netflix shouldn't be able to insist on a particular type of DRM for me to receive their service. Governments shouldn't be able to prevent me from end to end encrypting things. I should be able to opt into all this if I want more security, but it can't be mandatory. However all of these things are not technical, they are principles and rights that we have to argue for.

What I like about your comment is that it points out that all technical work-arounds are moot if people as a whole are not willing to stand up with pitchforks and torches to defend their freedoms. It will always come down to that. A handful of tech-savvy users with rooted devices and open-source software will not make a difference to the giant crushing machine that is the system.

And I'm afraid most of us are part of the system, rage-clicking away most of our days, distracted, jaded perhaps, like it historically has always been.
