We already eliminated Malaria carrying Mosquitos from large parts of the West with DDT and related techniques. Those mosquitos didn't manage to easily recolonize the areas from which they were driven away.
My understanding is that this isn't the case where Oxitec has done its tests, but this may be a feature of the size of the area where Oxitec is doing its tests rather than a feature of the method itself. (I suspect we did DDT everywhere at once, which would reduce the ability of mosquitoes to recolonize relative to a single test area.)
I think my main objection is that it's a few billions to do the sterile insect approach, and a few millions to do the gene drive approach, if that much. Insisting on a 1000x increase in cost to maybe please the public more rankles.
Oxitec has already PR problem with it's current approach where they can prove that all mosquitos don't leave ancestors and where they focus on disease carrying mosquitos that are invading species.

According to Oxitec:
...The economic cost of dengue is phenomenal and was estimated to have cost the global economy over US$39
“In 2015, there were roughly 214 million malaria cases and an estimated 438 000 malaria deaths.” While we don’t know how many humans malaria has killed, an estimate of half of everyone who has ever died isn’t absurd. Because few people in rich countries get malaria, pharmaceutical companies put relatively few resources into combating it.
The best way to eliminate malaria is probably to use gene drives to completely eradicate the species of mosquitoes that bite humans, but until recently rich countries haven’t been motivated to such xenocide. The Zika virus, which is in mosquitoes in the United States, provides effective altruists with an opportunity to advocate for exterminating all species of mosquitoes that spread disease to humans because the horrifying and disgusting pictures of babies with Zika might make the American public receptive to our arguments. A leading short-term goal of effective altruists, I propose, should be advocating for mosquito eradication in the short window before rich people get acclimated to pictures of Zika babies.
Personally, I have (unsuccessfully) pitched articles on mosquito eradication to two magazines and (with a bit more success) emailed someone who knows someone who knows someone in the Trump campaign to attempt to get the candidate to come out in favor of mosquito eradication. What have you done? Given the enormous harm mosquitoes inflict on mankind, doing just a little (such as writing a blog post) could have a high expected payoff.
