Reading the letter, it seems they are in direct violation of CA Code 2030. Could you shed some light on this?
Very good question. Especially in relation to the word "advertise".
My thinking exactly. California is a bureaucratic nightmare but they usually have something they can sink their teeth into before they start sending action letters. I ran a business in California for 20 years. I've received my share of letters from the state and none of them were completely baseless accusations. They do their research first. Funny that he chose not to answer that question. A little close to home maybe?
My guess is that he is just busy.
Anyways that Code 2030 is quite worrying. Generally speaking, I fear anything that forbids advertising something, since it can usually be twisted to condemn a broad range of behaviours and limit free speech.
