The Matrix Would Be a Troll's Wet Dream
One of the rules established in the Matrix series is that, since we're all living in a computer simulation, anyone can write a program that affects the rules of the "game." It's exemplified by the scene in which Tank pops in a floppy disk (because this world ended in the mid-'90s) and Neo instantly gains the ability to do gravity-defying kung fu. It's like turning on a cheat code. The idea continues when Trinity learns how to pilot a helicopter in the same way, and Morpheus gains the ability to make those sunglasses stay on his face without the ear parts.
His nose is really sore.
That's the whole seductive appeal of the franchise -- most of us would probably accept living under the thumb of an evil artificial intelligence if it meant gaining the occasional ability to hack the very universe into awesomeness.
As long as you're on the right side of the hacking, that is.
The Horrifying Downside:
In the first movie, the number of people who have this reality-bending ability is tiny, and they're all anti-Matrix freedom fighters using their abilities to free minds (even if, you know, they're leaving hundreds of bystander corpses in their wake). But if we generously accept the two sequels as canon, then after the third movie, the machine overlords allow us the choice to remain in the Matrix if we feel like it (because let's face it, the world outside kind of sucks). So anyone living in the comparative comfort of 20th century virtual reality is still subject to the rules of the game. Rules can apparently be hacked by anyone who has the time and dedication.
And those people are inevitably assholes.
Now there are all sorts of people living outside the Matrix -- anyone who chose to drop out and live in the cold, dark real world. So how do you think those people would feel about the ones who chose to remain in the pods? Remember that the first people with the urge to break out were all hacker types -- what do you think that crowd would do with their newfound powers? Imagine a reality in which the denizens of something like 4chan are actual gods, able to hack in at will. Imagine you suddenly start jacking off in the middle of a business meeting because someone from a higher plane decided it would be good lulz.
Take the blue pill and you see cat pictures all day. Take the red pill and you poop pretty much everywhere.
