A better example would be Brave or another smaller organisation.
Big multinationals have employees and assets everywhere that can be threatened.
However smaller organisations operating from a single jurisdiction can only be threatened by their local government (or at least with the consent of their local government).
I thought about Brave, but because they repackage Blink, the EU could choose to go upstream and target the engine rather than the browser, and Google ends up part of the equation anyway.
Firefox is in the US, right? Pale Moon is too iirc and they forked Gecko to make Goanna.
It's very hard for legal tools to change open source engines. Even if they compelled code changes from the engine maker, the downstream browsers could modify the engine code before putting it in their browsers. This is especially true for configuration type changes, like which certificate authorities to trust or which websites to blacklist.
