It's not about allowing swearing. It's a protest against these abnormal fines. When a rider comes from a stage, adrenaline is at its peak and accidentally says a bad word, it has to be understandable. This gagging of riders is not ok, we all want to get genuine emotion from riders after a stage. But we can't do that if they have to think about every word they say. They can't be so damn sensitive that the word fuck immediately scares them away. Kindergarten children already know these words, nothing will happen from these few words. It's a matter of principle.
