So Starlink has been so effective and so popular that — utterly unsurprisingly — it is becoming more congested and they're raising rates. This is good news and not bad. It's a strong sign that the model fundamentally works and they will be able to fund continuous improvements to meet strong demand.
I think that's a bit early to tell. If the launch costs + satellite costs don't add up to a very nice profit before the satellite de-orbits then that was a loss. This can look like it is working well until the number of satellites de-orbiting and needing to be replaced becomes larger than your temporary profits after launching the first constellation.
This is why other comms satellite operators chose to play it safe and use geo stationary orbits rather than LEO, those satellites live many times longer and you need far fewer of them. Obviously they are limited in bandwidth and latency but they are ultra reliable.
