Lets say we're talking about VCs and shareholders. Shouldn't the public enjoy the same expectations? Especially when we're just talking about a zero percent payback? I think there's a legitimate argument taxes exist for this sort of thing, but (1) taxes arguably are avoided in various ways to the point it's a currently broken system, and (2) this is a rare case where the government has a clear case for a specific amount of money owed by a specific company — why not keep it simple? If the grants aren't worth paying back at zero percent, the corporation shouldn't be taking them.
