Telephones have always been operated by for-profit institutions in the U.S. I much prefer at least one layer of indirection between my computer and the NSA. You put the government in charge of the internet and you'll get censorship.

I'm perfectly fine with the innovation coming from SpaceX and mobile operators with 5G to solve these complex problems. It works well by and large.

As for a publicly funded Twitter, meh, would you use it? Have you used government software? Rarely is it designed and run well.
