Here's the rub. Starlink is not and can not be profitable without venture capital and subsidies. It exists to funnel money away from taxpayers. It's a con built on lies like the rest. At least some people get to benefit from this, unlike people sold overhyped cars and promises of Mars colonies, but that's changing with price hikes and service degredations too.
What math do you want? The cost of launching infinite space ships forever is more than what subscribers pay. The satellites fall down in about a year and new ones need to be launched. The subscribers would have to pay for every single rocket launch. Right now American tax payers do.
The problem is you say this with certainty but have no numbers or evidence to back it up. How do you know the revenue from subscribers can't cover rocket launches?
Alright, this doesn't support your argument. That is a counter example that SpaceX ISN'T receiving subsidies. Anything else? I do appreciate the discourse though
