What does "true decentralized internet" mean to you? Surely if you want to communicate with people around the world, you need to rely on someone to transport the data for you across the country and the oceans. If not government, then who? Why would you trust them more?

Unless they are going to put FIDOnet back online (or is it still around?) you need a backbone for the internet, which means governments can always control and close it at will.

The mere fact the US is pursuing such an option is a demonstration of bad government that threatens and controls it's people with FUD.
