Some of the world's biggest social platforms were again under attack in France on Tuesday, as a consumers group announced it was taking them to court over "abusive and illicit" clauses and privacy issues.

The French Federal Union of Consumers, UFC-Que Choisir, said in a statement that it was taking Google, Facebook and Twitter to court due to their refusal to amend the terms and conditions of their social platforms. The consumer group wrote that it had repeatedly asked the social platforms to change their terms-of-use since June 2013, to no avail.
