You...know the Internet came out of government projects (DARPANet), right? It wasn't something that was developed by private companies out of the goodness of their hearts...
The original protocols and specifications still lie at the core of most of the Internet, and the infrastructure was, in large part, paid for by government subsidies to the telecom companies, the full terms of which many of them never fulfilled.
Even if one could realistically claim that "capitalism and capital investment" made significant positive contributions to the modern internet, the idea that any significant amount of those contributions would not have happened without the utter failure that is "trickle-down economics" doesn't hold water, either.
