About your claim that ownership as a concept is black and white, and no middle ground should be allowed.
> I don't understand what's so complicated about this, or why anyone would argue against this.
It's hard to understand the world if you see things through a binary lens - no ownership vs full ownership, or total support vs outright rejection. A more useful framework is to see what people support, reject, and tolerate.
For example, I totally support open-source hardware and software, and would love to see more of it. But I also tolerate proprietary hardware and software stacks, for many reasons. I'm definitely not rejecting the concept of private companies making hardware that runs their proprietary software and taking control over decisions about what software should run on their hardware.
From your comments, I see that you also support what I support, but you're totally rejecting the idea of hardware that runs proprietary software or not allowing you to run your own. So these calls for the government to step in and force private companies to disallow that concept are something I definitely can't support.
