I just want to point out that I've never heard anyone call for the eradication of mosquitoes that don't spread disease in humans, a major premise of the article.
Maybe it is a good idea but the consequences of it going wrong are disastrous. Like the Cane Toads that were introduced to Australia to wipe out an insect preying on sugar cane, that then became an endemic threat. But we're not talking about it just affecting flora and fauna, we're talking about something that could affect us. The cure might end up being worse than the disease.
Apart from the equilibrium dynamics, vampiric mosquitos also play a role in horizontal gene transfer and end up actually conveying immunity to the human population for various zoonotic pathogens that would otherwise spread to us: they help our immune systems evolve, and also contribute to evolution of humans.
