Company sells product for profit - they are liable for the product and all its subcomponents - there is nothing unfair about this - it doesn't matter if you found the components in a hole in the ground or on github - if you are selling a product based off it, you are liable.
For freelancers / oss companies - you can still sell services such as consulting or support - without selling your oss project - then its a service - not a product.
