It's a really interesting as it depicts well the entitlement of some people nowadays.

Yes you pay for you sub, you pay to access the content. You don't pay to get all the content, just to be able to access it. It works the same with solo games : you don't get to see the ending if you can't beat x boss.
Why would a mmo be any different in that regard ?

The skill requirements for FF14 are low enough as they are for everything that is not savage/extremes. You work to get past this content, it's part of the fun, and if you can't or don't want to, this is not the game's fault.
