"The European Commission is investigating Google for illegally favouring its own job ads service over rivals."
I'm anti-Google, but i don't see why Google shouldn't be able to favour it's own services over rivals. There's more than one search engine available. There's even Bing if you're insane enough.
"although some of the firms had admitted that agreeing to follow Google's requirements had improved traffic to their sites"
This really does look like some companies just want to complain about every. single. little. thing.
