How exactly does this work? Is this farming out the work of wget-ing URLs, followed by making those contents available on archive.org Wayback Machine?
It seems trivial to poison the uploaded content. And there's no way to validate that the content has not been tampered with in flight, unless a redundant fetch were performed in a trusted environment, at which point farming out the work serves no purpose.
Secondly, this doesn't solve the discoverability problem. Sure, after Blogger shuts down, a particular webpage on a blog might be preserved. But you will only be able to view its content 10 years in the future if you happen to already know the exact URL where it used to exist.
