There will probably be a lot more websites with expired certificates soon.
There are extensive options for automating renewal. I doubt that more than a small fraction using lets encrypt aren’t already using them.
Sometimes they fail to update. I would imagine that there are quite a few people who don’t bother setting up monitoring software to let them know if the certificate fails to update.
That’s why monitoring and digital calendars exist.
