Not going to respond to all of this, but the world has changed. And changed significantly. Game genres come and go. Game modes come and go. E-Sports are incredibly popular and a real career now. Content creators are real careers as well.
Franchise is a core mode for many of us that have been playing for 15+ years, but that doesn't mean it would continue to be a core mode for the game developers to continue focusing on.
I'd gladly fork over extra money if it meant the only mode I play, franchise, received real attention and development during the yearly cycle.
I don't know how popular franchise mode really is though. I watch a few Youtubers that run franchises regularly every year and enjoy the content. But when it comes to popularity it would be the MUT and H2H e-athletes and content creators that generate the most traffic.
