the one time I'll excuse AI being used in art.

I know what a lot of WHErwin said about this level applies to my thoughts about this, so I’ll post my comment from his video that I made some months ago here.

The ending to me could also link back to the section with the televisions earlier in the level, instead, there's nothing. No colors, no life, nothing broadcasted.

I interpret this as the idea that all of the conflict and chaos amounts to nothing, no matter which side you're on, no matter who believes they will save the nation when they're in power, all it will amount to is more division between these reds, blues and purples, no one will be completely satisfied and the cycle will continue. And thus it all fades to black, nothing being broadcasted as nothing matters to anyone anymore, staring into a blank channel with nothing to see.

(WHErwin’s) interpretation could also link into this, as political extremes eventually die down as well, both left and right, as the other side will eventually push back hard enough, much like a wildfire that ravages an overpopulated forest, it's all part of this almost natural cycle in the end.
