WHAT ? Adobe makes the final decision, always did, based on certification/distribution/whatever. It controls distribution of all desktop builds, and until very recently, it was Adobe who distributed the Android Flash builds, too (and still does do that for the betas).
To repeat the for the millionth time - where is that public (beta/techpreview/Idontcare) ARM Linux Flash build ?
Which other platforms are you talking about, not counting hacks, previews, announcements, unsanctioned builds, etc ?
Flash has nothing to do with computers, its bastard versions are available on basically anything.
Because TI is not releasing it, that is the problem. Their license is only for hardware OEM manufacturers. Let's say for argument's sake Nokia had the same thing (disclaimer: I have no idea if it does). It still couldn't give it to you as the Adobe T&C specifically forbids it. Back to square one.
