EmailGuard — library for detecting disposable or personal email addresses

That’s an incredibly off-base analogy. An e-mail address isn’t a payment form and receiving spam from a company that for no reason wants your e-mail isn’t the same as trading money for a product. I’m sorry if I offended anyone who uses this mildly dark pattern and wants to rationalize it, but you’re definitely moving towards user hostility in doing so, unless you can prove value to your users and show that value as an imperative to using a real e-mail address.
