They've went on record in the past saying themselves that the limited housing was their fault and an issue that still plagues them to this day. I believe I've even seen someone claim they admitted to rushing the content out, but I don't know for certain if that is true. They have expanded housing ward numbers in the past, added an entirely new district in Stormblood with the same amount of expanded wards, added apartments, and as others stated, have FC rooms. The only thing they have not put in, and I have no idea if this is even in the works, is instanced houses.

They have tried a number of times with little things here and there to help alleviate the problem without breaking something else. Saying they don't care, or its abusive is laughable at best, but you're unhappy with your product, so sure stop paying and playing. But I have my doubts that large amounts of people are going to do the same simply over housing as it really is something you can play the entirety of the game without and not miss a single thing except difficult choice in flooring, walls, and what could look cute in that corner over there.
