Providing free and fast broadband to all households and businesses is great. I’m not so sure about one state-owned organisation running the entire network though. I wonder if state assistance to local, publicly-owned local initiatives might be better.
Groups like B4RN (Broadband for the Rural North) have done a great job setting up local, rural broadband, building community in the process.
