They deemed AGPL untenable for their business and decided to create an OSS solution that used a license they were comfortable with and they are somehow "pernicious"? Perhaps take a moment to reflect on your characterization of a group that just contributed an alternative OSS project for a specific task. Not only that, but they used a VERY permissive license. I'd argue that they are being a better OSS community member for selecting a more permissive license.
