Reveal = show something that was hidden previously.

Seems like the appropriate word to use about a source code leak.

The words proposed by you are suitable for describing the consequences of a revelation, while no longer containing any hint about their original cause, so using them would have lead to a more verbose sentence for delivering the same information.

It wasn't hidden previously. It was fairly well-understood.

The CC source doesn't "reveal" a single thing about anything other than Anthropic internals. It says nothing about the industry at large, certainly nothing new.

And this:

    The words proposed by you are suitable for describing the consequences of a revelation, while no longer containing any hint about their original cause

doesn't make any sense. There is no "revelation" here. And the word "reveal" contains no connotations whatsoever about the "cause" of a "revelation".
