Private internet satellites is going to be a big market. Russian space program collapsing for quite some time and only being escalated recently. SpaceX paving a way for profitable private space business.
Satellite internet seem to me to be a niche thing, at best. It's extremely 'cool' but in countries rich enough to buy satellite internet high speed wireless infrastructure is nearly ubiquitous. Countries without the cash to fund wireless infrastructure also don't have the cash to pay for satellite internet. On top of that some customers who might otherwise have the resources and the need live in autocratic countries that may not be entirely happy with internet that isn't entirely within their control. It seems like that basically limits your possible customers to western style democracies in under-served rural areas or a few outliers like maybe marine applications, etc.
As a current Starlink customer, I can assure you there's plenty of market outside of the "nearly ubiquitous". I live just 30 miles from a small city where the average home is served by 400Mbps cable, yet until Starlink came along I was stuck with Hughesnet, which is reminiscent of a particularly high-latency 56k dial up connection. There are a couple thousand similar households just in my county.
Trust me, I empathize as I am in a similar boat. But we are a small, small market comparitively. We are expensive to service, low density, and low profit. Pretty much the definition of a niche
