It depends how they used them. The freedom of speech is the right giving people their right to express their opinions. But the opinion can't hurt another or any sensitive info. The freedom of speech does allow you to let your voice be heard, through a petition of a government action, a press, etc. Some sensitive info's include as fraud, obscenity (disgusting, inappropriate, or offensive to another), threats, personal address, etc. Therefore in my opinion, as long as your words or actions don't offend one or the other, you are free to use the freedom of speech all you want.
The compound subject is "Young Juan and his father." Both Jaun and his father are the subjects of the sentence, but because there are two of them it means there is a compound subject.
