What are the disadvantages of Starlink?

I've been hearing a lot about Starlink recently, but I'm curious about the potential drawbacks. Could you elaborate on some of the disadvantages of Starlink and how they may impact users or investors? For instance, are there any concerns about reliability, security, or scalability that users should be aware of? Additionally, how does Starlink compare to other similar services in terms of cost and accessibility? It would be great to get a comprehensive understanding of the challenges that Starlink faces before making any decisions.
