Newly Recruited Allies

Cannot find anything in the rules or rulings for this, and it never came up negatively before, but this was just ruled against. Can a newly recruited ally use it's abilities? The rules state:

To recruit an ally from your hand, play the card and tap the acting minion. If the action is successful, the ally is placed in your uncontrolled region, even though it is controlled, to indicate that it cannot act this turn (and the cost, if any, is paid).

And the ruling I received was that the newly recruited ally can also not use it's abilities. Now the rules show that it cannot act, and a ruling I recall clarified that it cannot block (actions done on the turn it is recruited or Heaven's Gated) but why can it not use it's abilities? i.e. Vagabond Mystic, Underbridge Stray, et al.

I am pretty sure you can use vagabond mystic the turn it arrives

Yes (assuming there are no other restrictions on the ally).

Some guy who might be, uh, me provoked this answer back in 1998. [LSJ 19980717]

The Ally is placed face-up in the inactive region when it is recruited,
which can serve as a helpful reminder that the Ally is controlled.
(Face-up cards in play are controlled, as a general rule. Face-down cards
in play are not.)

Another slant on this is "Can my Rom Gypsies tap to give one of my
Ravnos +1 stealth on the turn they are brought into play?"

Or "Does the Ally I just brought out count for an Autarkis Persecution
I call later on the same turn?"

The answer to both is "Yes".

Well, I carry no conviction over here (Stockholm) even though I am the one who is usually asked for rulings (since I tend to keep up with them) in my neck of the woods. So I needed these answers posted, especially since I would've won their League game that night but for this. They also did not allow Spying Missions to be stacked (they burned and replaced) though I stated otherwise. And I'm going to play an EC here, sheesh!

Excellent!
See you there.

Correct answer from jamesatzephyr: freshly recruited allies can use their non-action abilities the turn they are recruited.
