1) False dichotomy. 70,000 scans is still 70,000 scans. Even if there were a million texts in, it still doesn't remove the fact that tens of thousands of people used that one method. 2) The plural of anecdote is not data. I bet none of your friends drink Bacardi Breezers - yet you wouldn't deny that they're popular (I assume that's what the yoof of today drink!)
