I'm just looking for a helpful, actionable response. All I've seen so far is "X is bad" (not actionable) and "Let's ban X" (not helpful).

What good will it do you that there's an international ban on DNA databases when corporations use the impossible-to-stop one anyway to discriminate against and target you or the police use it anyway to throw you in prison.

The most helpful course of action imo is to learn how best to cope with this new reality. How should we set our expectations when our DNA is public and searchable? Are there behaviors that would once be safe but will not be in the future? I think those are the more relevant questions.
