I'm curious to know why this is any more or less shady than an app that uses ads to monetize? Those ads use a ton of bandwidth and share a ton of information about you? If they're just passing some packets through your IP for web scraping what's the big deal?
Bright Data offers an SDK for app developers to monetize their apps this way (https://bright-sdk.com). Maybe I am naive but this seems exponentially better than monetizing by sharing every tidbit of information Google and FB can get about me as I move through the web. Genuinely curious why this is so negative?
