That's like asking if anyone still uses Windows XP. Of course! And they'll never stop.
Years from now, when Adobe stops patching it and every major browser has dropped support, there will still be web services that say, "Please downgrade your browser."

Their customers are locked in and they would only lose money if they took the time to modernize it.
I think the Flash 0-days of the future are only going to get scarier.
