Not to be silly, but how do regular people find out that a Flash Player update is available? People who don’t have an Adobe ID for example? People who have never been to “Flash Runtime Announcements” community and seen:
Visit our Get Flash Player page to download the latest Flash Player release.
People who generally see a pop up window that says, click here to Update Flash Player?
And than pull the trigger. Even if the pop up window is not from Adobe.
Don't crucify the messenger.
