Apple wanted to make FaceTime open sourced and they couldn't because of a patent troll. I don't even think we can get into the complexity of today's hardware systems without running into any number of reasons why that stuff can't be "open-sourced". It's great that super-techy people want to be able to repair their own devices (and there's no reason currently why you can't) so I feel like the current right to repair movement, and especially people like Louis Rossman, are doing a huge disservice to the ideas behind people's actual rights to repair devices they buy when they conflate them with "open-source" and completely ignore the fact that 99% of people don't care.
Unless they find a way to show people what the upsides and downsides of the current situation are objectively, they're never going to get the support they need. As it stands, they're being misleading at best and downright lying at worst to try and push a narrative that gets to the end goal and, as soon as the lies come out, it'll push the momentum backwards instead of carrying it forward. The number of people with expertise to actually fix most of these issues with these complex devices is incredibly small and dwindling and opening that up to anyone and everyone without some kind of plan in place is just going to spectacularly backfire.
