That's not even possible. The github repo is public and forever. And even if it went away, any version created in the past 2 years can read your wallet, so you'd only need to find one person who has an old copy of Armory. AND, the wallet format is public: https://bitcoinarmory.com/armory-wallet-files/
There's no way to make you cry
I was thinking of the unlikely scenario were all my computer explode, Github dies and no-one publically keeps a backup of the program, code or documentation and all I have is my paper wallet. I went ahead and marked this risk as acceptably unlikely
I might have an old version of the paper wallet though ...
