Of course they did, why do you think the companies demanded full immunity. You dont do that unless your worried about your products safety. Think sky diving, experimental therapies/medications, etc. You dont ask for waivers if you know your product is good, and how do you know that? By proper trials and shit, but fuck it, we proably dont need it this time. lol.

And ahh yes, given full immunity to any "foreseeable" issues.

When you burn and shred the evidence, of course its unforeseeable. Fucking idiots signed their waivers anyway.
