Most people who were members of socially bad organizations throughout history weren't bad people or doing bad things, but willingly joining and serving a support role for such an organization is itself morally dubious. It's actively helping enable their activities.

For example, if someone got a job on a shark finning boat maintaining the knives, they're still complicit in shark finning even if they're never touched or seen a shark in their life.

And even if their actual role was spying on and helping detain Americans for arbitrary reasons, nobody's going to slap that on their resume. They'd say they were a data aggregating administrative officer.
