I know of no one, aside from myself, who has succeeded in escaping the grip of the FI. There may be people in here, or elsewhere that I know, who have escaped, but I don't for sure about it.
There is a very revealing reason for this. It is almost impossible to know if a person has released themselves from the FI unless you actually live with them. You can't easily tell from a distance or a casual acquaintance.
To the trained eye you can see the embedded constructs in place, so you can make a good guess when it is obvious the FI is alive and well. But as with romance, people are able to put on a good show when connecting to others via the internet or for short periods.
It is amazing how all is revealed once you spend substantial time with another. That is the real test.
