Well
if they're going to claim that your open sauce creator in Nebraska is liable for any bugs in the code, then I can see the open sauce guys doing 1 of 2 things
1.(most likely) Abandoning open sauce creation.
2. Becoming full time licencing lawyers writing up terms for companies to use their open sauce stuff.... and sueing the arse off anyone who tries using it without paying.
Alternetively, like all good EU laws, will just be ignored by the member nations
Biting the hand that feeds IT
