Google last week filed a response in a 6-year-old antitrust battle with the EU, which has charged that its search ads unfairly promoted its own shopping service and blocked rivals. The response addresses a supplementary statement of objections the European Commission sent to Google this summer. The commission’s original statement of objections narrowly defined online shopping services to exclude services like Amazon, and it failed to take into account the broader dynamics of online shopping, which is “robustly competitive,” Google noted.
