From what I read, Oath holdings is Verizon (and others) that owns Yahoo mail pro. If you had a paid Yahoo mail account in the past and paid for it to keep it secure, you will now be billed under Oath Holdings. Long ago I had paid for my Yahoo mail back in the late 90's after it got hacked and only then I could recover it because I proved i was the owner from my payment receipts and card# (before paypal). The new price scale is about $35/year for a pro ad free account, compared to the $20 I paid in the past.
