I guess I'm not sure why you doubt that. The standards are pretty clear that "does not advance SPSP's goal of promoting equity, inclusion, and anti-racism" is a failing grade on the DEI section, and that anti-racism in particular is not merely a thing the conference does but a core component of their identity. I'm sure if you sat down with them, they wouldn't frame it as abandoning anything; they would tell you that social psychology inherently touches on diversity and authors who believe their papers are unrelated should maybe think a bit harder about it.

Please cite how it is a "failing grade" versus not receiving the bonus for it. The bottom score is "not applicable", not "not satisfactory" like it is in other areas.
Reviewers did not receive the statements. The assessment of the statement was only a small input into the committee making final decisions primarily based upon reviewer feedback.
OTOH, it may get a little harder to publish research where your study population / sample is all-white-wealthy-undergrads.
