Flash isn't an open standard by any useful definition.

Sure they specified the container format, bytecodes, and data structures — but everybody had figured that part out a long time ago because it's obvious and easy to capitalize on by developing an extractor. The runtime APIs are incredibly hard to reverse-engineer, comprise the vast bulk of the Flash implementation, and are the entire reason for the plugin's instability.

It's like saying that Windows is a completely open platform (save for the patents) just because Microsoft publishes a stable userland ABI and fairly comprehensive API documentation for downstream developers.

Gnash is no further along than ReactOS.
