It has more to do with the practical considerations of doing the greatest good for animals as a whole. Take a look at this article by a self described longtime vegan and vegan advocate:

If Vegans Replaced Plants With Insects, They'd Harm Fewer Animals ...

... On the face of things, the question seems moot. Vegans don’t eat animals; insects are animals; vegans therefore don’t eat insects. End of story. But this simple little syllogism betrays the very real possibility that vegans, by virtue of their quest to reduce animal suffering, may not only be permitted to eat insects—they may be obligated to do so. ...

... All that said, with the insect option now on the table the vegan equation has fundamentally changed. The choice is no longer between incidental or non-incidental deaths of obviously sentient creatures. It’s no longer between the mice crushed by a combine and the pig taken to the abattoir. Instead, it’s now between the intentional death of animals who likely suffer minimally or not at all (insects) and those that clearly do suffer (bunnies, deer, mice, etc.) when plants are grown.

As a longtime vegan and vegan advocate, I’m well aware how this argument threatens the vegan identity. Of course, it’s much easier to declare, “I don’t eat animals or animal products” than it is to blur the lines that serve as clear ethical commandments. But as the prospect of eating insects gains traction, vegans may be forced to acknowledge the inconvenient fact that including these critters in our diet—yes, eating animals—is an essential way to achieve the ultimate vegan goal of reducing the suffering of animals who we know can suffer.
