I have to flag this title as linkbait: this is a testimony from a marketing executive, saying stupid things about open source. It's not in any way the position of the supreme court of any country.
If it rendered GPL ineffective, then the company couldn't use GPL software at all (if you can't comply with the copyright license, the work doesn't automatically become free to use however you like).
Well, if the law doesn't state "You can use GPLed software without complying with it."
If it rendered GPL ineffective, then the company couldn't use GPL software at all
That's not the case at all. Plenty of countries have laws the make parts of various licences invalid, and it doesn't mean you can't use the software - it just means those clauses don't apply.
