5G is not supported by most phones. It requires a lot more infrastructure (base stations) than traditional GSM because of shorter range, so operators worldwide are currently on a concrete craze destroying the environment ever more. And it opens a lot more avenues for surveillance. All of that without bringing any measurable improvement of life to anyone.<p>Why the hell would i want free-software stack for that tech? On one hand it'll be used to legitimize 5G in the first place which is far from consensual topic, even in tech-friendly circles. On the other hand, i conceptually appreciate the idea to run my own GSM stack, BUT 5G is mostly worse (if i want short range i'll just do wifi thanks) and even if i run my own stack, commercial operators will never peer with me so my users won't be able to talk with anyone else (pretty useless).<p>In my very personal view, cell phone networks are useless pieces of tech that need to be replaced with proper Internet infrastructure.
