Read the article. This software was "expressly designed for use by stalkers and domestic abusers". Apple and Microsoft have not expressly designed anything for those purposes.
Re read the article. You are quoting the US DOJ statement, not what the company or persons in question have said. If you go to the cached version of the stealthgenie website (since the real one is gone) that is not the case. They were marketing it to employers and parents of teens.
Regardless of your opinion on that matter, the statement you quoted appears to be a falsification.
