I mean that might be part of it, but also because the internet developed out of the ARPAnet which was a United States Department of Defense project, at a time when the United States was one of two superpowers (right as the other superpower stopped being a superpower or for that matter a state), in a world that already gave pretty heavy weight towards English as the lingua franca in international institutions after World War II or simply because it was the lowest-common denominator in a lot of the world post-the British Empire. English had a lot of wind beneath its wings. Still does.
