Because if I want to provide an app to like 5 people I know personally, I am soon forced to do so via the Playstore due to Google disabling sideloading on Android. So now I am forced to inform myself about all the bullshit documents I never cared for beforehand. Yes I know what I am allowed to do with my users data, no I don't send it to some data brokers, yes I already comply to privacy laws and whatnot. Just requiring some official document that you have to let a lawyer take a look at is beyond me.
