I think the idea is that you can tell people "hey, if you're suffering from abuse, you can check a websites footer for this icon to get help"
I'm not trying to be dismissive, but I genuinely can't imagine this helping anyone. I am completely open to being wrong though.
I do think there is real value in being able to report domestic abuse without leaving an obvious paper trail. Call logs can be accessed by the account owner, I imagine a lot of people don’t know how to clear their history or aren’t confident enough they can do it correctly, etc.
It’s some small amount of peace of mind for victims who file reports, and with a cost of “adding a fake social link and a devs salary for a month” I’m pretty okay with it even if it literally only helps a single person. Bandwidth well spent.
