I don't care if Flock is used to cure cancer. It's being used to oppress millions of people right now. We need to stop the harm now. It can be reintroduced later when we have a less psychotic administration.

On a more 'logical' note: compare the number of people it theoretically could help, to the number of people non-theoretically being harmed by it right now. The latter number is higher. On a purely emotionless, mathematical point of view, it is a net negative. (And this is a charitable rationalization; using a theoretical future to justify a present harm is illogical)
