Pretty sure any Americans willing to go out of their way to use a niche FOSS platform like Lemmy are already aware of this and trying to make change in the little ways they can. You’re kind of preaching to the choir. If you want to reach anyone go to facebook or Twitter or reddit (where your post will then be deleted by a power tripping mod)
Edit: also for clarity, how do you know this isn’t public knowledge in the US? Have you been there? If so, where? It’s not like all 300 million people in the US have the same viewpoints.
If not, I can tell you right now that our national politics are ultimately decided by a few thousand people in the most rural parts of the country who barely know what the internet is. If you look in places like NYC or Minneapolis or Seattle then you will get a much different picture of what people think than in Texas or Florida. People do what they can but when you have the entire government and billionaires against you it isn’t exactly easy to make changes that people see on the other side of the world.
Not that I want to defend AMD but the reason they haven’t been able to is because HDMI is a private spec and the HDMI forum specifically forbade them from releasing the driver they tried to publish a few years ago (even though the firmware with the actual implementation is in the GPU itself and still proprietary). That’s why 2.1 works on windows and not Linux with the past 2 gens of AMD GPUs.
