Dropping support entirely sends a clear message: if you want your page viewed from a mobile device, do it right!
There are still dozens of lies about Flash still flying around.
The #1 lie:
Flash on a mobile device gives the end user full web experience. Eeeaah, with a couple of "IFs", like IF the page is acceptably sized for a mobile device, IF the page does not rely on mouse overs (N/A on touch screen device), IF , IF
All mobile devices besides iOS based ones always supported Flash.
When the original iPhone came out, there was only "Flash lite" on mobile phones. It was NEVER intended to provide "full web experience", and it didn't. It was merely a programming language to allow Flash developers to write (simple and crippled) apps for those phones. SEVERAL YESARS LATER, Adobe released "real Flash" implementation, which stayed in beta for months, till (the middle of?) this year. All Apple competitors jumped on Flash with the hope that they will sell this crap to the user as "competitive advantage", and that it would somehow compensate for the lack of quality apps and widen the developer support (most notable examples: Xoom and PlayBook).
