This is going to be a dumpster fire. Musk has already sued, and even if the case goes against him, he'll appeal. The first thing they'll do is demand and injunction stopping these new guys from providing a product. Irreparable harm blah blah blah. If that gets denied they'll find someone who will grant it. That's the way the American legal system works. Rich people sue and then appeal until they get the decision they want. This won't be different.
