This is not true. Flash uses the embed element for cross-browser display
and did so before there was accessible Flash.

Actually, Section 508 in the US is basically WCAG-based and doesn't
include validation or many other P2's.

As far as not having valid code, it doesn't mean that Flash can't be
used, it means that other compromised need to be made.  If you want
valid code with Flash you need to either:
1) require javascript from your users
2) use proprietary IE-specific comments
3) use a valid technique that breaks accessibility in the most widely
used user agent for blind people

Does using the embed element cause problems for automated testing tools?
Really?  They seem to parse it now fairly well...

Is this a joke?  If so, I don't get it.

If you think that this is all about the Flash player then your view is
too narrow. This is a problem for QuickTime, SVG, WindowsMedia, Real,
and others.  

What will happen is that users will reply on javascript more to write
the needed code on the fly, after passing validation.  This goes on now
with a lot of dynamic javascript web work - the application/page is
declared 'valid XHTML' but the new content that is added dynamically
isn't necessarily.
