That only seems to apply to dumping as an action by international firms, intended to damage domestic companies, and the rights domestic companies have to address it. It's not strictly applicable between two local firms competing for customers.

I see, I don't think there's a difference between domestic/foreign firm when it comes to dumping in EU. I think that you can't operate with loss in order to crush competition. But Google might have it covered with other sources of revenue coming from "free" users.

The big difference is say a Japanese Steel maker dumps a bunch of foreign steel on the US market, then suddenly disappears... there's a structural crisis because the US steel industry has to rebuild from scratch. Or that's the argument anyway.
