It's crazy to say it doesn't work well in tandem... I mean, it's demonstrable, If it didn't work, people wouldn't use it, but they do. And there is no other way to reach users in some places. Starlink can reach users that only a long range wireless solution can work for. There are some other long range wireless solutions, but this one does work.
Look, I don't like Elon, I don't like monopolies, I'm not a secret shill for SpaceX, but I can admit the truth right in front of me. You don't have to stretch the truth to say Starlink isn't a good system for the vast majority of people, so why do it? Why create a false narrative? Why get all defensive about a technology?
And finally, I do not see any reason to care about an extra 5 ms latency.
