"We love Apple," said the Adobe ads. "What we don't love is anybody taking away your freedom to choose what you create, how you create it, and what you experience on the Web," the Abode ad concluded.
The Web ads linked to the Adobe.com website where the company's co-founders published an open letter defending Flash.
Adobe's move comes two weeks after Apple chief executive Steve Jobs published an open letter in which he defended his decision not to allow software developers to use Flash when making applications for the iPhone, iPod Touch or iPad.
Here are some excerpts from today's open letter as it was written by Adobe's founders:
"As the founders of Adobe, we believe open markets are in the best interest of developers, content owners, and consumers. Freedom of choice on the web has unleashed an explosion of content and transformed how we work, learn, communicate, and, ultimately, express ourselves, "Adobe's letter reads.
"We believe that consumers should be able to freely access their favorite content and applications, regardless of what computer they have, what browser they like, or what device suits their needs."
"Adobe's business philosophy is based on a premise that, in an open market, the best products will win in the end ? and the best way to compete is to create the best technology and innovate faster than your competitors." ..." More recently, we've done the same thing with Adobe Flash technology. We publish the specifications for Flash ? meaning anyone can make their own Flash player."
"We believe that Apple, by taking the opposite approach, has taken a step that could undermine this next chapter of the web ? the chapter in which mobile devices outnumber computers, any individual can be a publisher, and content is accessed anywhere and at any time."
