At this point will FFXIV collapse if all mods and third party tools disappear?

The game was profitable with less then half the current player base and at a time when it delivered more content per patch on an actual 3 month cycle.

I think they stated the game would still be profitable enough if it maintained 200-300k players back when arr first launched and had around that number of people playing during launch. But with how big the player base is now and how long mods have been around and allowed as long as it remained hush hush they would lose a decent chunk of players. They would still have a large playerbase but would lose a good chunk if they decided to go hardcore full ban mode on modders or had some software to detect mods. They seem to not mind mods as long as people don't openly talk about it then that's when actions get taken.
