Arbitration typically tends not to be as neutral as a court. A court will always look how laws apply in a particular case. Arbitration may not do that. Arbitration takes power away from the consumer. Arbitration is not a court of law. It’s a dispute between an individual and a company. Don’t know how things are in Switzerland in this regard but I fear that it’s not as neutral as a court of law would be. Especially as the arbitrator is pre selected by the company.

Also in their TOS “No Class Arbitrations, Class Actions or Representative Actions.” i.e. if the company would screw over dozens of people they can only complain one by one even if they are all the same case. If a class action or class arbitration could occur the company screwing over dozens of people it could be viewed as a whole hence it might be determined that what they are doing is systematic, and if it would be in court it could be seen as illegal.
