quote: 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.
