From the article - 'The activities of another multinational offering quick and convenient services – the car hire app Uber – has also raised the hackles of authorities in Paris in recent months. The company has faced fines, legal challenges and its drivers physical violence since it began operating in the city in 2012.'

Uber's legal activities are still running. They're having a fair success from what I know.

Uber's illegal activities have been challenged in court and closed. The reason for the particular way it happened is mostly that the company tried to bully its way through regulation by ignoring it like it did in some US cities. The police then decided to search of french Uber executives' homes, and they came to their minds quite fast afterwards.
