2) Put a copyright notice saying that they are FREE TO USE THIS CONTENT On THEIR SITE if they are in a related business niche. (No need for a link back, even).
There would be a "cache" at Google .just because they say they don't offer a "cache" of a page.. and they say they respect "no cache" and "no index" on a page.. doesn't necessarily mean they do not keep one for themselves ..many things indicate that in fact they do keep "cached" versions of everything in separate indexes..just means that the "cache" is not available outside G.
Occasionally we have seen "glimpses" down the years of these G "internal use only" indexes and caches.
So they would have something (2 )to compare..with (3)..and likewise if an original publisher changed their mind..I assume that in the latter case G would consider it to be a "civil or commercial dispute" between yourself and the publisher and thus probably would keep both versions in serps until a court made a decision.
