In some ways this seems endemic to all organizations with >1000 or so people. It's crazy the extent that white nationalist orgs have infiltrated Law Enforcement/US military.

That being said, in many ways companies/organizations are simply biased samples of the cultural milieu, so I'm not sure there is an easy company-level policy for changing this. Given the Banjo/Clearview.ai KKK/alt-right stuff, the fear of radicalized tech employees is definitely a matter of real concern, but it's definitely a hard problem.
