Congrats, you found out that the game is successful, and is making lots of money. The cash shop isn't actually affecting anything, only generating part of the profit that you listed (how much of it, we don't know). The knock on effect is SE likes XIV even more, and wants to invest more into it (which was my point), which is why your point about us getting nothing good from the cash shop is wrong.
Also "The EU datacentre wasn't made possible by the additional funds, it was always possible." is wrong. We didn't get an EU datacenter initially because they did not have the resources to implement it. The devs explained what the funds go towards in the opening keynotes of EUfanfest 2014, and unless the devs are flat out lying then this means that the cash shop has indeed helped bring us more content and infrastructure improvements.

Anyway, I don't want this to turn into a pro/con mogstation debate because I'm against the cash shop too, I'm just saying that there are pros to its existence that should not be ignored.
