That’s how I envision a second (free) Internet. People getting together and building a free alternative Internet with as much off the shelf tech as possible just to have a second option, politics be damned.
Even though the Internet can probably be infinitely large, it’s still only one. What if the public have a choice of two or more internets? That would introduce competition, especially a free one.
I wouldn’t personally be so fast, as others, to be dissatisfied with a slower global communication option. To communicate globally or even nationally is no small feat, even slowly. If it gets the job done and it’s lower in price or free, I might not care if it’s as fast as the Internet we have now.
It doesn’t have to be everything the Internet we are using now is. It just has to facilitate the exchange of information over long distances between people as an alternative to the current options.
People use packet radio to send messages and I imagine that’s slow. But it gets the job done and it’s free once you have the equipment.
