Using 3rd party is always a risk. Just see the app that have added its well known 'radar'...
The very first line in the post you link to says a tunnelling software doesn't directly control anything in the FFXIV client, and is therefor not breaking any rules. In other words, it's perfectly fine to use. Now, if that tunnelling service all of a sudden decided to add a feature that displays information in your FFXIV client (like the radar app does), then it will be breaking rules, and then you can get banned for using it.

That said, Square Enix does state in the EULA that they can ban whoever they want for whatever reason, so always use common sense
