To protect the elites as the other commenter said. Start with the claims of a person who led a bunch of wars after getting Medal of Honor:

The same patterns kept happening over and over from there. The politicians got to play politics. The big, war contractors made billions. Their CEO's millions. After the drafts, the eventual "volunteer" army of mostly poor or working class kept dying for their BS about protecting "freedom" and "democracy." Look up Operation Ajax and compare to how that event is treated today to know plenty about what DOD does in the world. ;)
In the second, the legal line is not crossed. It may be crossed at some point by an adult person that can bear responsibility for his actions.
I would not work with both; I can understand how can one not be a hypocrite by choosing to work with the latter and not the former, but not the other way around.
Is it the right moral choice to protect the privacy of a cheater? Maybe, I don't know, I'm struggling to answer that to myself, let alone judge others.
Is this spyware used to find out if someone is cheating? If so, it means you'd install it, and violate their privacy, without knowing if they are a cheater, so the point is moot.
My point is that privacy in a relationship is a relationship thing, and the moral choice for me would be to not interfere in other peoples relationships. This includes not judging you if you use spyware on your wife.
I'm not sure this is true. There are often clear boundaries, like secretly observing them in public versus accessing their private phones.
> privacy in a relationship is a relationship thing
but it's also a privacy thing. Is domestic abuse a relationship thing? That would also interfere with a relationship.
