Living in constant fear because of your gender and where you were born is direct harm. Being controlled by the opposite gender is a direct harm. Not being able to become educated because you are female is a direct harm to them AND men(and those in between).
But in this case why stop half way? Why sell them a phone (the OS) in the first place? Isn’t this (just like the app) condoning the behavior? Isn’t being their ally the same? Doing business with them in general?
Protesting the immoral behavior only by means that don’t really hurt your own bottom line is not actually doing much except cement the hypocrisy.
Are you not arguing and attempting to impose a stance on others right now? You don’t know which countries we are from and if our governments are aligned.
There’s a thing called human rights and we should all stand up for them.
