Earlier quoted context omitted.
It’s an intrusion. Would you be outraged if you came home one day and there was a plumber fixing your sink? “Oh hi, don’t worry about me, just fixing your sink. Let myself in, hope you don’t mind” You didn’t even know your sink was leaky let alone called a plumber.
If your home had a ruptured pipe, that was spraying sewage all over the sidewalk, I think someone stepping onto your property, and turning the firehose of shit off would be behaving ethically. Trespass to save people from themselves is one thing. Trespass to save the public is quite another.
So yes, it's actually fixed, but now you know that someone you don't know broke into your house without permission nor supervision and you don't know what he's done/seen/stolen in your house.
