Forum:Veiler and the graveyard

I was checking some rulings and found those : Effect veiler : This card will negate effects that activate or apply on the field. It will not negate an effect that activates in the Graveyard. If you target Exiled Force with Effect Veiler and your opponent Tributes Exiled Force to activate its effect later in the turn, the effect of Exiled Force will be negated

Costs : Costs are paid before the activation of a card, not after. You pay the cost then announce your intention to use the card.

Activation is when you declare an intent to use a card

So here are my questions :

1) Since tributing a monster is a cost for exiled force, lonfire blossom, stardust dragon..., their effects should normally activate in the graveyard, and yet, they are negated by Effect Veiler, why is that so?

on the same logic, we have Grave of the Super Ancient Organism vs Stardust Dragon :

Grave of the Super Ancient Organism : All face-up Level 6 or higher Special Summoned monsters on the field cannot declare an attack or activate their effects

"Grave of the Super Ancient Organism" does not negate anything. It prevents you from activating the effect, so you cannot even Tribute "Stardust Dragon".

2) How can Grave of the Super Ancient Organism negate an effect that "activate" in the graveyard?
