Adobe CC for Linux - this theme is dicussed for years and years. But nothing happens.
Adobe has no plan to support Linux, not in the past, not now and probably not in the future either. Your petition won't change that either.
In my opinion, Linux is also not really suitable. There to much different Linux derivatives. If Adobe supports one (if its possible) then users of other Lunix derivatives demand that their version is also supported. This will be a huge expense that can no longer be realized economically.
