No, I think we're seeing things like Nextcloud (Germany) and Deepin (China) pop up in other countries as nations realize the USA is a sketchy imperial power. GPL is becoming a strategic choice to ensure sustainability.
Europe and China are looking at RISC-v for example to eliminate the issue of licensing sanctions by the USA.
Fuchsia could become popular but I doubt it will overtake Linux when the reason Linux is popular is because of the GPL license. Also, the man hours of volunteer work that went/go into Linux would not be matched by Google, or Google competitors. Would Apple or Microsoft really spend time helping Google Fuchsia? I could be wrong but I think Linux is safe for another few decades.
I'm more worried about MIT licensed independent vendor neutral projects like Redox OS that could get strong community followings while people don't realize the implications of using non-copyleft licensing for their works.
