ELI5: Why are AAA games increasingly removing local multiplayer (split screen) game types?

I understand that online multiplayer is a huge component nowadays. We still live in the real world though! When I have people come over to visit my place, I like to do a bit of split screen. Games like Evolve won't allow this, meaning that I simply can't fire up that game which is a huge shame. Why?

Along with the answer about selling multiple copies, it also requires more resources out of the machine to run a split screen game.  The CPU needs to process the movements and actions of twice the characters, and the GPU has to render 2 separate screens.  this ups the load on hardware, and typically a hit has to take place in either FPS, resolution, or texture quality.

Target MP gaming demographics are typically college age to 30+ year old males.  this demographic doesn't typically live close enough or want to travel to their friend's house to play with them.  This is more done as kids or middle/high schoolers.  It doesn't make financial sense to spend money to develop something used by a fraction of your purchasers, especially one that could in theory hurt sales.
