You don't have to fly an approach down to the minimums you can elect to increase the minimums to whatever you like (within reason) due to any reason you decide on the day. All approaches (save low viz auto lands) are designed to get you down to a visual segment to land. If your visual when you loose the ILS and can remain visual whats the problem continuing? I would have no problem with continuing however without knowing the full circumstances of your friends approach its hard to say what should have been done, however a GA is a safe option and can't be criticised even if its not what you or I would have done.
