Sorry, my arguments were not meant as FUD, but as challenges to be solved. I like the idea of every piece of software being free, but those points need a solution to make that work. I am of course aware of Red Hat and its business model. It mostly works, because there needs to be a "standard" distribution for commercial Linux platforms. But there is expensive software sold to corporations where the open source model just wouldn't work. Software, which costs tens of thousands per seat, where there is almost one developer per user. This eco system would break apart.

And for the second point, you misunderstood me. I would be very happy if every firmware would be open source, so everyone can see how the device works. But whether it is ok, that every user is free to change the installed software is a different question. If you brick your TV changing the firmware, that is up to the user. But safety-relevant software is another thing. At minimum, liability is affected, but for example for cars, they might need to be recertified before they can be used on public roads again.
