Rest assured that if things continue to work as they have over the last year, retirement will come, but we don't know when.
We don't know, but we can guess. If the freebitcoin team doesn't make any improvements, we can expect their site to stop operating after October 10. I assume so because their domain registration expires on that date.
Just imagine what will happen if they forget to renew it. In that case, there will surely be people ready to buy their domain and redirect traffic elsewhere.
