We added that to the description because otherwise folks searching for "k9" or "k9mail" or "k-9 email" couldn't find the app or got pushed to sketchy malware pretending to be K-9. If Play's search worked, we wouldn't have had to stick keywords in the description. (But also, it wasn't against policy when we did it 5+ years ago. And I absolutely don't mind them asking us to change it. But the zero-strikes removal thing pisses me off.)
