I mean… OP interacted with a privacy feature. The tracking was already blocked, but if you go further, you might be interested in privacy in other ways. It’s not an entirely unreasonable place to assume a user might be interested in your other privacy products.
That being said, I don’t know that I would put all my privacy eggs in one basket with one company. I use a variety of products, free and paid.
People who ask for this either don’t know what they’re asking for or know precisely what they’re asking for.
