Streaming content wars?

It seems like every big name telecom and media company is coming up with their own streaming service. It's interesting to see some companies allowing their content to be on other platforms, while some companies have decided to get their content off their competition's services. I'm already subscribed to Hulu, Netflix, YouTube TV and Amazon. How many more am I going to have to subscribe too because of these content wars? Which strategy do you think will work better from a company perspective? Competition or collaboration?
