Looks like they're aware of the issue, if not the timing and that it expired 193 days ago and all of Go Daddy's reminders were ignored. According to their webpage- "When a product is coming up for renewal, we send out specific email blasts regarding those products on the 90, 60, 30, 15, 10 and 5 day marks before a product is about to expire."
So technically someone started ignoring this 283 days ago.
It doesn't have to involve a lot of money or effort. I have my domain registered with PairDomains and they sold me a certificate for $10 per year. All I had to do was download it and move it to the directory Apache httpd expects. Way less trouble than setting up a free certificate from Let's Encrypt.
