Is my hearing deteriorating or am I hearing what sounds like PC has reached this wonderful Gazebo-bastion of good old school "I like my victories when they come hard" line of thinking?
Please no. Just no.
I don't know what you are exactly saying by PC (personal computer?). If you are accusing us of elitists, you are missing the shoot (Well, ElliotS is a bit elitist, but we pardon him). The issue here started by OP and some other players disliking that VP had become harder. I complained about it too, but for different reasons. I've simply changed my difficulty and now I'm happy again.
Now, we could discuss if deity has to be so hard that no one has ever beaten it yet. Apparently Gazebo like it this way, but Civ has always been beatable at its hardest. So, do we go as the lead developer wants to or do we claim him in mass to lower difficulty to something more reasonable? On one hand this is CBO, it is Gazebo's beast so he can do as he likes, on the other hand, being so difficult at the hardest level may turn some players away. Personally, I think that it is better when the best players can beat the hardest level 50% of times, but I respect G decision, as this does not affect my ego (too much).
What really turns people away, is expecting a hard game, but finding it too easy for their expectations in the early game, then finding that they are not able to win in their usual difficulty level, not finding the correct strategies for late game (those are too common complaints in reddit). If there's a disclaimer so no new players get fooled, then they would have more realistic expectations and we'll receive fewer critics.
Particulary in this thread, we might have been rude to OP, but he wasn't very constructive to begin with. He was just complaining of difficulty, in rather despective or dismissive terms. Then he tried some easier games up to warlord, where he still failed, but instead of asking what he can do to improve, he just stated that the game was ruined for him, after putting 4000 hours in it (BNW or VP? he does not specify). At least he tried again.
We are quite open to criticism, when it comes with a reasoning. It could really be that the late game is too hard, but we need something more specific to work with. Specially when we asked for this behaviour in the first place to avoid boring endings.
About specifics. I still don't know why all AI banged against OP. Was it because they found him weak? Was it because OP was about to win, triggering 'despair' mode? Was it because he bullied everyone and failed at diplomacy? Without knowing this, we can't give advice on how to overcome the problem.
