They...aren’t. Leaving aside the question fo whether identifying the “male gaze” as a cobtributor to problems with the algorithm’s output would be blame passing when the entire context is taking responsibility for and addressing problems resulting from the choice of algorithm (hint: no, it wouldn’t), they initially identified that as a potential thing the saliency algorithm might* be biased for, constructed a test, and determined it was not a factor, so they are saying “male gaze” wasn’t a problem.

Kneejerk reactions to the use of the phrase without considering anything about what it is being used to say aren't helpful.
