I know several people that are approached with "load our SDK and make money pay per install on your userbase" type of deals for these residential proxy things. I've been approached myself by unknown (I didn't respond) actors offering to monetise my browser addons with more or less the same. For the actual end user it's definitely not above the board. Public notes: https://www.reddit.com/r/androiddev/comments/ao27tu/my_app_with_1million_installs_and_100k_monthly/eg02u38/ https://www.reddit.com/r/androiddev/comments/ao27tu/my_app_w... https://www.reddit.com/r/androiddev/comments/ajfc7w/question_about_oxylabs/ https://www.reddit.com/r/androiddev/comments/ajfc7w/question... https://dx.doi.org/10.14722/ndss.2021.24008 https://dx.doi.org/10.14722/ndss.2021.24008 I have never seen actual informed consent before in ANY of these for the final end user; most of the targeted apps are general rubbish (think flashlight app requesting location permission and contacts type of BS). At best it would be buried deep in a ToS or EULA somewhere, and even that's fairly rare. Using a very very stretched definition of rewarding users, you could argue that "allowing the use of a calculator for free" is the reward for being an open proxy. If you find any example anywhere by the implementors ("oh, it's the sdk includer's fault they aren't saying anything, we're totally above board...") that there is anything approaching informed consent, I would love to know some examples, because I've never seen one in these. (I would dearly love to be wrong here)
