How would this situation indicate a slippery slope of decision-making? Mozilla didn't know about OneRep's CEO's history; nobody did until Krebs uncovered it.

It goes back many years before Kreb’s wrote about it. Optery has a nice write up of the situation here:

Their earlier statement said they were aware of the CEO's history but were assured that part of his life was behind him. From that statement on March 15: “We were aware of the past affiliations with the entities named in the article and were assured they had ended prior to our work together,” the statement reads. “We’re now looking into this further. We will always put the privacy and security of our customers first and will provide updates as needed.”
