Nah, that's just standard deontological vs. consequential thinking. If dishonesty is approached in consequential terms then it becomes just another act of (fully generalized) aggression -- something you don't want to do to someone except in self-defense or unless you'd also slash their tires, to borrow an Eliezer phrase, but not something that's forbidden in all cases. It only becomes problematic in general if there's a deontological prohibition against it.
Looking at it that way doesn't clarify the distinction between lying by commission vs. lying by omission, though. There's something else going on there.
I don't know what you just said. For example you wrote: "that's just standard deontological vs. consequential thinking." What does that mean? Does that mean that I have in a single comment articulated both deontological and consequentialist thinking and set them at odds, simultaneously arguing both sides? Or are you saying I articulated one of these? If so, which one?

In secret, an unemployed man with poor job prospects uses his savings to buy a large term life insurance policy, and designates a charity as the beneficiary. Two years after the policy is purchased, it will pay out in the event of suicide. The man waits the required two years, and then kills himself, much to the dismay of his surviving relatives. The charity receives the money and saves the lives of many people who would otherwise have died.
Are the actions of this man admirable or shameful?
