Nonsense video, underlying problem is monopolies and private companies who develop the standards, not what browser you use.
If the standards are fully open, transparent and not concerning then it would make no difference if you use chrome and firefox because everyone would use same basis.
Also chromium team is not purchased or owned by Google, most volunteers are normal people, developers or security researchers that code on it in their free time. You can fork, modify the source as you please but that does not change the argumentation about web standards and how build or control them.
