Thank you very much for highlighting this important topic. #FLOSS is indeed the way to go for both hardware and software.
Just one quick note from my side: I wouldn't go so far to describe Open Source as the "enemy" of big tech. As you mentioned above, some big tech companies, like Meta, actually embrace the concept by releasing their LLM models with a free license.
Other companies, such as Suse or RedHat, are heavily relying on open source software to run their businesses.
