Pinboard does archiving if you pay the extra fee.
I don't understand how people think they can provide web archiving without charging. All I wanted was a service that archived pages on my behalf for a reasonable (i.e. very cheap) price.
And then they could make those pages public and combine payments from multiple sources in order to keep the archive alive, so more popular pages would be easier to keep archived for everybody.
You're right - nobody can provide archiving without charging (at least not without a hidden cost _somewhere_, including censorship).
In the system my company is building, you would either bring your own hosting (in your closet, on your desktop, whatever), or pay a cloud provider for the same. Our stack is open source.
We've run the numbers and it looks like you'll be able to do a _lot_ of archiving for quite cheap.
Then once n individuals are paying for their own archives, they can opt to network together over a peer-to-peer network to share their archives with eachother (or perhaps even charge for access to some of them)
