The emails purported to come from individuals, but were (1) written in an aggressive, legalistic style, and (2) directed at individuals who were not subject to CCPA and not equipped to deal with regulatory demands of it. This caused significant anxiety on the part of the individuals who received this email, since it implied they would be subject to legal action if they did not provide a sufficient reply. It caused them to take significant action -- e.g., to research the law (that they aren't subject to), to determine if/how they could comply with a CCPA data access request if they had to, to consider retaining legal representation, etc. It came off as some kind of scam or mistake, but one that had to be taken seriously. You could read some of the blog posts from people who received these emails to understand the effect it had on them. It might also help you to read the email they received and imaging receiving the same for a site for a personal blog or one-man shop.
