This is normal and by design. They fly super low, way in the upper atmosphere. This means they can't stay up there for more than 3-4 years. It's partly to reduce latency, but more likely it's just a part of the trick to keep SpaceX in business. Starlink is their biggest customer, a lot of the launches are just for Starlink. And they need to keep on launching, otherwise the network will fail. This means Musk can pump the huge pool of investment money from Starlink straight into SpaceX. This keeps them in business to keep funnelling money from taxpayers in the form of NASA grants into SpaceX. Musk then used that SpaceX money to invest in xAI, which was used to absorb a lot of the debt created by buying Twitter.
All just a scam, pumping money around to keep filling their pockets.
