"Commercial speech" refers to advertising, or more precisely, speech that "proposes a commercial transaction". It does not refer to speech that is charged for. Newspapers and books are fully protected by the First Amendment even though people pay for them.

Unfortunately, there is a received "professional speech" semi-exception to the First Amendment, explaining things like how there can be laws against charging money for legal advice (pure speech) without a state license. I assume that's what California is thinking here.
> Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
It clearly distinguishes the press as different from speech, but teaching someone certainly seems like it would fall under normal speech.
