I believe there is even an article about it on CBR still, and plenty of articles in the Jack Kirby Collector. This is a matter of history and common knowledge not some crazy theory. It is infeasible to me that anyone reading the early JitM comics can come away believing that Blake was always supposed to be Thor in disguise - that the Kirby Lee retcon was actually always the plan.
Canon-wise just go read the Roy Thomas retcon. It points out very clearly that Blake was a real human and that story hasn’t been retconned. This is a separate issue as it is not seeking to revert the first retcon, just utterly change it.
