It contradicts exactly what you said
This story is not about people leaving. It's about them not getting as many NEW customers as they thought.
But they say:
Gross additions were on target, but churn ticked up slightly and unexpectedly.
That's literally the opposite of what you said. They are getting as many new customers as they thought, but people are leaving.
Although nobody is talking about building enclosures to attract lightning to your bathroom...
There is a degree to which rabies in humans is rare because people are afraid of it. And fatal shark attacks are rare because humans don't like to swim where the dangerous shark varieties are. Etc..
That doesn't mean this isn't a good idea -- mosquitoes are a disease reservoir that is typically much more infectious, and choosing bats because they suppress mosquito populations* seems likely to be a good choice. It's just an explanation for why people don't love bats. I didn't care about bats much but my parents would tell me to avoid them due to the rabies risk.
* This of course assumes it's true. I've read that there's little evidence that bats eat enough mosquitoes to make up for the fake that they eat the things that already eat mosquitoes.
