Ruling A question regarding a ruling on Rare Candy

[PMJ]

Q. Does Rare Candy override evolution-preventing effects such as Fossil Aerodactyl's "Prehistoric Power"?
A. Yes, you can use Rare Candy when Aerodactyl's Prehistoric Power is in play. (Sep 18, 2003 PUI Rules Team; Jul 22, 2004 PUI Rules Team)

Q. Can I use Rare Candy on my Pokémon to go to their evolutions if either Kabutops or Omastar from Skyridge is in play (with the powers/bodies that stop evolution)?
A. You could not use a Pokémon's attack or play a Trainer card to evolve your Benched or Active Pokémon, unless the Evolution card you would be putting into play comes from somewhere other than your hand. So Rare Candy cannot be used, but Wally's Training can (when referring to the Active Pokémon). (Aug 5, 2004 PUI Rules Team; Aug 12, 2004 PUI Rules Team)

What makes Kabutops and Omastar so great that they can stop Rare Candy? Is it because Kabutops and Omastar explicitly state that the cards can't come from your hand?

Kabutops
Omastar
Rare Candy
Aerodactyl

That's how it looks for me. And they note the exception that Wally's can be used and the inference is that it's OK since it comes from the deck not the hand.

Yeah, I know. Maybe I wasn't clear enough, but I'm asking why Rare Candy can't be used to override Kabutops's Primal Whatever and Omastar's Primal Whatever, but it can be used to get around Prehistoric Power.

Prehistoric Power
No more Evolution cards can be played. This power stops working while Aerodactyl is Asleep, Confused, or Paralyzed.

Primal Aura
As long as Kabutops is your Active Pokemon, neither player can play Basic Pokemon or Evolution cards from his or her hand to evolve Benched Pokemon.

Primal Stare
As long as Omastar is your Active Pokemon, your opponent can't play Basic Pokemon or Evolution cards from his or her hand to evolve his or her Active Pokemon.

There is a subtle difference, and this IS a point of confusion.

You play the Pokemon you evolve with Rare Candy from your hand; Primal * prevents Evolution cards coming from your hand.

Prehistoric Power says no more evolutions can be played. But you are not 'playing' an evolution. You are playing Rare Candy, and the evolution is an effect of playing Rare Candy, so it is allowed.

But I still think this is a contradiction. Primal Aura/Stare say you can't "play" Evolution cards from your hand. If Rare Candy is not "playing" an Evolution, why does it not get around Primal Aura/Stare?

The party line seems to be that Prehistoric Power only prevents "normal" evolution, but allows evolving as an effect from something else. Primal Aura/Stare prevent any Evolution cards coming from your hand, regardless of what caused them to be played.
