If they are running noscript then why on earth would you expect
them to have flash enabled?  :)

(1) Flash presents a greater and less controllable privacy exposure
than Javascript does.

(2) Flash is more frequently blamed for obnoxious ads than JS.

(3) Without javascript support a great many flash sites simply don't
work because the copy-and-paste flash version probing used depends
on Javascript.

(4) Flash (and other plugins) are commonly 'known' to trigger firefox
crashes, not so for JS.

Perhaps I'm all wrong— but I don't think your suspicions pass a sniff
test. Someone should try measuring.
