In the old days, when it was the US vs the USSR, we had CIA vs KGB. We coveted sources and methods, and there was a multilayer cover of who and what was gathering intelligence.
The current scheme of things seems to make public our sources and methods, never done before, in any intelligence gathering community. The old way, just keep it quiet, it just disappeared. It allowed one options, secured your sources, and gave some sense of security for those to follow. However being part of an ongoing election campaign ad makes one a bit nervous. Ya think.
