I think they mean using it for other purposes like general use. Basically whatever else you would do on a browser, including pirating. Like just open it and use it for all the random stuff you do in your day to day, and if a lot of people do this, it can add additional coverage for people that need to use it for evading dictators and whatnot

i use it for Facebook because i don’t want the Facebook embeds in many websites to even pick up that i have the same ip as the dedicated Facebook browser
