In this diff archive.today was converted to archive.org

This should not happen for a couple reasons. Archive.today uses a different capture and rendering engine it is sometimes more accurate than Wayback, it is often a go-to site for when Wayback doesn't work or doesn't work well. There is also the issue of content drift, converting from provider to another shouldn't be done arbitrarily unless there is a compelling reason as it can cause content drift. Users who create archive.today links may do so for a reason and their decisions should be given priority unless there is a reason to change via bot (site is going down, has known bad archives, link not working).
