>>> why does IOS, Andriod, ect each have there own API gateway vs sharing one
You need to be aware of some lifecycle aspects when dealing with first versus third-party clients. If you don't have experience with third-party being a key component of your business model then this is hard to grasp.
When you list these mobile clients, I immediately assume that these are your first-party clients. These are clients which you deploy to various stores and manage completely. There is some chance that you are supporting old versions, but you are mostly in control and can drive the support lifecycle by deprecating old clients when analytics suggest it is OK.
When you have clients that are critical to your business (some weird set-top box) that you can't just deprecate, then it starts to become viable to do something like this. Your main system can evolve and grow leaving only a single system to maintain for these special clients. Whether it's worthwhile is going to be completely dependent on the value of the client. It's massive improvement in the quality of life for your backend team and those responsible for supporting the client.
