I used to work on sports gambling apps and yet I never once gambled using the real production app. Because I saw the data. And behind those data points are real people having their lives ruined by some growth hackers and psychologist PMs trying to increase session length. I know how the sausage is made. I practically have the gambling addiction hotline number memorized because it was required to be on every screen.
Pretty much everyone I know gambles on sports and for most of these guys its like a $50 bet, not a lot of money. No more than a few beers these days at a bar. People get addicted to anything, lets work on having people receive treatment if things become a problem rather than ban everything that most users are using responsibly. Might as well ban video games of you really want to get some people out of some deep holes.
