It's reported as an official answer from Lukas Litzinger

Yes. There is no rules about additional cost.

Maybe in the next release of the FAQ we'll find something.

In the meanwhile you can:

1) trust what's reported in the BGG Forum post only for red herrings

2) apply Lukas' ruling about additional costs to all the cases (Fetal AI comes to my mind)

3) ignore that post

FFG doesn't answer here on the forums.

You have to put your questions here: http://www.fantasyflightgames.com/edge_atencion.asp. And wait for an answer, that may or may not be given.

Lukas Litzinger is the lead developer for Android: Netrunner, so the reported ruling can be considered official. Again, you must trust in what the user reported (but I don't see why to lie for a game rule)

There is no guarantee that this ruling won't be reverted in next version of FAQ or that it will be part of it.

I have to add this post on BGG: http://www.boardgamegeek.com/article/10981314#10981314

AFAIK, user byonczimmer is officially involved in Android:Netrunner FAQs
