This seems like a really empty, hollow pledge to me because the employers of these signatories fall into two categories:

1) Companies like Google or Facebook that already have "databases of identifying information...to target [for advertising] individuals based on race, religion, or national origin." That data exists. They're not going to delete it. If legally subpoenaed, they will turn it over.

2) Companies like "Poncho"[0] a cartoon cat that tells you the weather. They do not have this kind of data, and they never will, so there is zero chance of these signatories facing a tough decision to keep their pledge.

Maybe I'm too cynical, but I don't think employees of type 1 are going to actually quit their jobs, or go rogue and delete their employers' data, and I don't think employees of type 2 are ever going to face any choice.

So how would this pledge ever demand any kind of action from signers? Somebody help me out here? It feels like the equivalent of tweeting "I really really don't like Trump".
