If you dig through the history of
https://wiki.openstreetmap.org/wiki/Remapping you'll find lots of urls
that showed what impact the data redaction for the license change was
going to have. But probably none of those are still functional.

I think that's the best bet at this stage. There a a few websites that
render OSM at differents snapshots in time, but I don't know of any
that have snapshots pre/post odbl.
Contributors have put a lot of effort into making the diff as small as
possible, and even in areas where the loss was significant (parts of
Australia for example), OSM recovered amazingly quickly afterwards.
