Winer ends with a suggestion for Adobe:

Adobe might want to consider, right now, very quickly, giving Flash to the public domain. Disclaim all patents, open source all code, etc etc. That would throw the ball squarely back into Apple’s court and would frame the question right now in its most stark terms.

That’d be an interesting move, and it would certainly shake things up. But what if the source code to Flash Player is — as many would wager — a huge steaming pile of convoluted C++ horseshit? It’s sort of like what if Microsoft open-sourced the Internet Explorer rendering engine. It’s not like anyone who is now using WebKit or Gecko would switch to that just because it was opened — or that WebKit, Mozilla, and Opera would suddenly be obligated to or even interested in adopting IE-specific web features.

I think John Gruber misses the mark here: the idea is to nullify Apple’s claim that A) Flash is too buggy to include and B) Apple can’t do anything about it. Precisely because of Apple’s open source love (noted at the beginning of the article), Apple could feel pressure to help remedy A because B wouldn’t be true any longer.

“Huge steaming pile of convoluted C++” would be an esotericism to the masses that just know, “it’s now open, and Apple still won’t support it.  WTF?”
