Somewhat. Webstandards are voted upon, and I believe Mozilla is part of those organizations.

However Google could always choose to ignore web standards and do what they want. And due to their massive market dominance this would effectively enforce this overnight for over half of the internet.

The reason they may not, is the EU would take them to court over that. The US no longer believes in stopping companies from ruining shit though.

It’s not a goal, just a happy accident they found along they way!
