You are attempting here to defend Adobe against Apples effort to harm them, after all the disinterest Adobe has shown the Linux world. Way to go man. Frankly I support Apple 100% in the quest to marginalize and hopefully reduce Adobe to ashes. Yes I hate flash that much and even more hate Adobe for promoting it while doing little development and stabilization of the product.MS may try to keep people from copying their own products (yes, apple does this as well, and much more vigorously). But they have never once - please, try to give me an example here - declared that a company that has spent millions of dollars developing a product that they can't allow their users to run it on top of windows. Not once.
I actually see this as Apple sticking up for the many users that have had to endure flash on the web for years now. You may not see it that way but Apple can have a far greater impact on Adobe than we as individuals can.
As to Apple being open to developers I'm not sure how some of the opinions being expressed here are even possible. Apples development tools are open source, you can build your own compiler chain right now using to different code bases, can't do that with MS at all. In the case of LLVM and associate tools, they are getting deployed in a number of projects outside of Apple. Apples contributions here are very significant and constantly dismissed with no good reason that I can see.
Heck, for my taste MS is even a little too developer friendly - i think the platform would be better if they didn't put such a priority on maintaining binary compatibility with decades old code, but I can see why a 3rd party developer might like it.
