Google’s priorities are not always the same as mine. Trust, security, compatibility, and safety are all important, and the terms are sometimes used somewhat interchangeably.
Trust and Safety
This is about as safe a site as you will find. Everyone is free to come here. No account or password is required. There’s no advertising, and I’m not selling anything.
Thanks to that, the search engines and browsers haven’t cared that a secure connection isn’t created when you visit here.
Norton Safe Web has dubbed the site SAFE, without threats or even “annoyance factors.” That doesn’t mean nobody will be annoyed by anything they find here. Norton defines annoyance factors as “Items that don’t necessarily do harm, but are a nuisance, such as joke programs or a site that isn’t what it seems.”
