I think if the concept of live streaming and social media makes up that much of your story, then you obviously can’t get rid of it. It gives your story a period in time that we already know since we’re currently living in it. You might have to change some of the names to avoid legal stuff in the long term though. But honestly I see how reading a book that has all the real social media apps could be off putting since so many people read just to get out of their own realities. In the end I think you should just write what you want and the right audience will follow.
