Would you rent your unused internet bandwidth for a passive income?

A friend suggested I do this. I said it was risky, and he was upset. He told me this: ''A picky person will never have anything''. I am that picky person. But I read about it and there are risks. The income is passive indeed and we only need to turn the computer on. But what if our data will be sold? I am very tempted to try because I need money. But I know there are some risks. I think that Google already has our data and we don't earn anything. Would you try this? Is it risky to rent our unused internet bandwidth?
