The title says that the US government /intervened/. As the article explains that happened, but also that that intervention wasn't the only reason why TRON didn't succeed.

The title should have been "Japan tried to build an operating system for the world, the US intervened although it quickly changed its mind, but a Japanese Windows PC seller used that intervention to boycott it". Or maybe just "Japan tried to build an operating system for the world, here's why it failed".
