I believe it's breaking podcast feeds being served with WordPress.com, because iTunes doesn't support Let's Encrypt certificates.

This may not affect a lot of customers (since WordPress.com doesn't support PowerPress for feed generation), but I know some podcasters create feeds by hand or with other apps.

This issue will cause at least some podcasts to disappear from iTunes without warning unless you can coordinate with Apple to fix it.

Do you have an example? We have already implemented workarounds for iTunes. If they aren't working I would love to know the specifics so we can fix it.

Just the confirmation from Apple's podcaster support team that iTunes doesn't support sites which use Let's Encrypt. (I don't use WordPress.com myself.)

I've just posted a request for examples in popular podcasting groups, and I'll let you know when/if I get responses.

Can you elaborate just a smidge? Is WordPress.com, for example, not encrypting content when it's requested by iTunes? (Thanks!)

Yes, we have some targeted exceptions for incompatible clients.
