This isn't marry magdalen in a grilled cheese sandwich this is monopolizing a market, Which by US law is illegal. They are breaking the law, end of story.
try using google to look at the track records of these company's, then defend them.

This one happens to be true. There's a reason today's hybrids are using the problematic many-little-batteries-strung-together format. They are unable to legally use larger NIMH's.

I know, it's Wikipedia, but with lots of external references.
Patent encumbrance of large automotive NiMH batteries - Wikipedia, the free encyclopedia

The patents are due to expire soon, but advances in Li-Ion chemistries will make it largely irrelevant.
