But, none of that makes any sense. Cheaters and lag are consequences of playing online, whether you pay for it or not. PS+ improves the online experience in other ways, that many feel are worth the added cost.
Lag is due to issues with the P2P connection between you and your opponent; we aren't paying Sony to ensure that both you and your opponent have decent internet connections.
At the end of the day, the state of online play is better on PS4 than it was on PS3. For many, the magnitude of the improvement is worth paying for. If it isn't worth it to you, no problem! Some people are willing to pay for Kraft Dinner (that's Macaroni & Cheese in the US, I believe) while others are willing to eat the no-name brand to save a few extra cents, even if it doesn't taste as good. To each his own!
Let me offer another example: Last night, my brother-in-law got angry (like, legitimately angry) when we decided to go for gelato. It's more expensive than ice cream! The difference in taste isn't worth the extra dollar! While we were out, he took a picture of the group with his thousand-dollar camera, instead of using the free camera that came with his phone. My brother-in-law is a jackass.
Everybody has their own priorities. It seems like you have a little agenda here, hoping that - I can only assume - if you yell "Sheeple!" enough times, everyone will abandon the PS4 and then... the PS3, your platform of choice, will become relevant again. What you don't realize, is that one of the biggest benefits of paying for online play is that it has separated us from jackasses like... my brother-in-law.
Also, you.
BTW - I don't understand why this is an issue for you in the first place. Playing outside is free, so why did you pay money for a video game system and software? Sending smoke signals is free, so why do you pay money for internet access? Counting on your fingers is free, so why do you own a computer? Friggin' sheeple.
