Algorithmic Justice League — research-impact: Over 70 AI researchers publicly signed letter defending AJL's research following Amazon's challenge to the Gender Shades findings on their Rekognition system

NoteThe source text directly confirms the core claim: 'more than 70 researchers' publicly signed/defended AJL's research following Amazon's challenge to the Gender Shades findings. The source also confirms the context about Amazon's initial dispute and mentions NIST's validation study. The claim states 'Over 70' and the source says 'more than 70' — these are equivalent expressions. The temporal reference 'as of 2019' cannot be contradicted by the source since the source page doesn't specify when this statement was written, but the claim's timeframe is consistent with the historical sequence described (Gender Shades paper, Amazon's challenge, researcher defense, and Amazon's 2020 moratorium announcement).

NoteThe source text confirms that the Gender Shades paper exists and that it involved Amazon, but it does not address the specific claim about 70+ researchers publicly signing a letter defending AJL's research in response to Amazon's challenge. The source is from AJL's own website and focuses on their mission, origins, and general accomplishments, but does not provide details about the specific research-impact metric claimed (the number of researchers who signed a defense letter as of 2019). This specific data point is not mentioned in the provided source text.
