That would put full blame on the tech staff and let the C-suite get away. The success of a software product is measured by sales and user base, so the more successful their sales and marketing are, the higher the damages will be for the tech staff.

I am of the opinion that companies and their management should be personally liable for damages caused by bad software, not their employees. They created the structure, hired everyone (and perhaps didn't hire QA), and invested in it to make a huge profit.
