As someone directly involved in financial AML/KYC, I'm seeing companies being required to use these lists (including this canadian one, due to inclusion in, for example, the opensanctions aggregate list) without any oversight as to what is on them, for the purposes of denying accounts to applicants.

If there were lists of left-wing terrorist organizations I could make a strong argument for their inclusion.

Further, if there were lists of unfairly-persecuted groups and individuals I could make an argument for whitelisting.

This list-making turns out to be extremely powerful, especially when the government is using companies to enforce what the government can't, and companies are outsourcing the data collection so they can wipe their hands of it, the power given to those maintaining, aggregating, selling these lists is insane.
