It's really not hard to understand, and if you're a CTO you should probably be aware of how this works. It's an abuse when a company uses their dominance in one area (like search) to undermine their competitors in a different market (like product comparison and shopping).

That's the case here, and it was the case when Microsoft got in trouble for bundling IE with Windows.

I'm actually glad to see this ruling. It's nice to know there's at least one place in the world where the government still cares a little bit about not letting giant corporations take advantage of their citizens.
