The issue here is a company like this would need to operate in the red for several years. You just can't penetrate the market in a meaningful and profitable way during the first few years when 95% of it is controlled by 2 companies. You also need a hefty wallet to get started with suppliers to be able to negotiate cost effective components or you'll be priced out by completion. It's a daunting task for any new player. Many startups have tried and failed here. Block could do this. They have the hardware experience and the deep pockets to operate at a loss for the first 3 years. Jack mentioned looking into it. I'm not sure if anything has been done here.
