If the kickstart/Workbench will be released, there will be a chance for Amiga to survive!
What a load of rubbish. How will releasing it save the Amiga? It wont.
Both "kickstartroms" and Workbench adf's are freely (if not legally) available on the internet. Nostalgic people who want to use UAE are not "held back" too much from doing so.
The only way to "save" the Amiga is to pump money back in. By releasing kickstart / workbench you are REMOVING one (albeit small) source of income from the Amiga development community.
