I don't understand. How is it being "abused"? If the attacker has actual DNS access to create ad.{legitimate domain}.com, then Let's Encrypt is working as intended. So what if they're hosting malware—that's {legitimate domain}.com's problem. Let's Encrypt has absolutely nothing to do with content behavior safety, only domain validation and encryption to keep data away from prying eyes. This title is no different from "Chairs Now Being Abused by Criminals". It's nonsensical and completely unrelated. Do you care that criminals have started using chairs to sit down (gasp)? I don't think this even belongs on Hacker News.
