The streaming war isn't over yet.
Netflix had a hilariously dominant market position, with a subscription to them being basically a no-brainer. As media companies have developed their own streaming platforms, Netflix has been losing quite a lot of content. Previously a Netflix subscription would give the user access to pretty much anything they wanted to watch, now Netflix only provides a small fraction. Sure, Netflix might still be the largest streaming platform, but that's not saying much anymore.
The real war is going to be retaining their user base over the coming years, as more and more people realize that getting access to the content they want means paying >$100 / month for half a dozen different streaming services. People ditched cable television for streaming because cable provided shitty content at high prices. Now streaming is rapidly becoming the same.
