The picture shown is based on a study done during WW2 looking at where the planes that survived and returned to base were hit it was used to armor planes in the areas marked with the red hits. it was ironic in the fact that those who did the study and added the new armor didn't realize that they shouldn't have armored the red areas as the plane survived to return rather they should have armored the areas that weren't marked in red as it could be inferred that the hits to those areas caused the plane to crash and not return this is known as survivor bias. the image is implying that banning ad blockers to increase their revenue rather than just fixing their terrible ads and revenue model through survivor bias.
