I was going to say that I was surprised that enough "normal" users had heard about the Pentagon news story that it would make a difference.
Then I remembered that the app store rankings [1] seem to be based on activity from just the past day or so.
And so a lot of "plugged-in" users switching to Claude all at once then would be enough to briefly send Claude to #1, since the migration would be sizeable in comparison to the normal daily download baseline.
But we can also expect that this would probably be just a blip for a couple of days, as it's unlikely to make much difference in the baseline ratio for the general population.
