Anacron sending out a cryptic e-mail due to a hung cron job is a primary bug in and of itself. Either don't send out an e-mail at all, or send an e-mail that doesn't confuse people while leaving them no avenue for follow-up. You have enough deep knowledge of the system to intuit the underlying problem from that message. Most users don't---and to put it bluntly, you're not Ubuntu's target audience.
I agree that the cron job should be fixed so that it doesn't misbehave. But since that's not going to happen overnight, and hung cron jobs are a thing, and anacron is part of a default Ubuntu install, and Ubuntu purports to be user-friendly, we need a fix here as well.
