That's very charitable. A less charitable view might be that their concern is that regulatory bodies and other executive agencies are standing in the way of personal and corporate profits, and that overturning Chevron means that the courts can now cripple the ability for federal agencies to function by overruling the reasonable interpretations of statute those agencies have been operating under all this time and instead limit them to only the most narrow interpretation of the law. Law that has, for decades now, been being written under the assumption that Chevron exists, and not with the expectation that an adversarial judge will try to undermine the intention of the laws being passed.
