Activated ability means you can choose when you use/activate the ability. As opposed to automatic abilities, which happen at a certain timing only, or continuous abilities which are applied continuously (thus the name).

GDS has an automatic ability. You can't choose when to use its ability, you can only choose when to cast GDS. When you do, its ability is applied immediately.
