More on how luminati and other "residential ip" providers work here: https://medium.com/@xianghangmi/resident-evil-understanding-...
Between your link, and the luminati faq's, I definitely have more questions then when I started looking at these articles.
I asked, and they are only interested in partners with 100k active users a month. They REALLY REALLY wanted to talk to me over skype. Right, like a legitimate company with that many users is going to use luminati.
The use case of luminati is almost entirely grey/black hat. Their history is laughably sketchy. Unless anybody knows of any apps that use the SDK and ask for permission, I suspect that FAQ page is just for show. Again you have to be a big player to even use it, it's not a stretch to believe they don't "enforce" the consent rule.
