Hydrogen is notoriously good at diffusing through seals, and even through metal. Negative internal pressure does make this harder, but it might be a problem. Handling hydrogen is generally a hassle, so it was probably chosen to make life easier/cheaper at the factory.

So is helium. That's why you can't cash in on the impending global helium shortage by buying up helium tanks.

We could always just Kickstarter a fund to buy the US government storage facility.

Exactly this. Efficient hydrogen storage is a huge open research question. Even keeping the helium sealed can be difficult enough.
