The Business Insider article is indeed godawful.
The MIT article is, obviously, much better:
And of course the actual scientific paper is better than that:

The Business Insider idiot fundamentally misunderstood pretty much everything about the research; it basically has NOTHING TO DO with defeatubg “passive” stealth (shaping and materials to reduce a radar return) which is the key to the B-2, F-22, F-35, etc. All it concerns is defeating one particular type of “active” jamming, which is what non-stealthy aircraft, missiles, etc. often employ.
Thanks.
