You need to take the long view and consider the long-term evolutionary 
traits of technologies. Flash is dieing but it just doesn't know it yet:

  * Knowledge of the internals of SVG spreads more quickly than that of 
Flash because of the open file format, "view source", the thorough 
documentation and the open source projects around it.

  * SVG is making serious inroads into handheld devices. I believe will 
eventually be as standard on newer devices as J2ME, Bluetooth and MMS 
for newer phones.

  * SVG is probably going to be integrated right into the core of some 
GUIs like KDE and Gnome -- perhaps a more mainstream OS also

  * As an open standard, you could even imagine a graphics vendor 
building an API tailored for implementing SVG on top. Flash would never 
get that. Flash will never be built into an operating system.

  * I've observed that the GIS world is in love with SVG (early niches 
are important as a technology gets a foothold)

  * Adobe and Corel have a huge chunk of the graphics tool market and 
they are both huge investors in SVG

  * Canon is talking about putting SVG directly in printers

  * SVG can be displayed in Java applications. Flash cannot.

  * SVG can be much more easily integrated with XML data sources. That's 
why it is a good match for the GML language used in mapping. There is a 
whole new market opportunity opening up called "Smart Graphics." This is 
why Corel cares about SVG.

Macromedia has not out-Microsofted anybody. Microsoft can pull a 
"Windows Media Viewer" on them whenever they feel like. Actually, SVG is 
the only thing that would make it uncomfortable for them to do that. 
Arguably, Macromedia is Microsoft's bulwark AGAINST SVG.

You're asking "why are open standrds better than proprietary ones?"
