Hugh Pickens writes: "Businessweek reports that Adobe has taken out newspaper advertisements in the Wall Street Journal and the New York Times today and posted an open letter to call out the tablet-computer maker for stifling competition. "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," the letter states. "No company — no matter how big or how creative — should dictate what you can create, how you create it, or what you can experience on the web." The letter is part of a widening rift between Apple and Adobe. Two weeks ago, Apple Chief Executive Officer Steve Jobs wrote a 29-paragraph public missive panning Adobe’s Flash as having “major technical drawbacks.” U.S. antitrust enforcers also may investigate Apple following a complaint from Adobe, people familiar with the matter said this month. Adobe has also launched a banner ad campaign to let you know that they love Apple. The two-piece banner ads are composed of a 720 x 90 pixel “We [heart] Apple” design, followed by a 300 x 250 pixel medium rectangle that reads: “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.”"
