They are releasing sterile males of one specific species, infected with a naturally occurring bacteria that naturally infects them in the wild as well. It's hard to imagine a more targeted or less objectionable method than this. If you won't accept this method then you're essentially arguing we should never attempt to reduce the invasive mosquito population by any means, which I will have to respectfully but strongly disagree with.

I can imagine many ways this can backfire. The simplest is - the targeting you’re assuming may not be actually what happens. It may be that some number of bugs released are different and have an unintended side effect. What gives this private organization the right to run this experiment on all of us? Will they assume liability?
