This is not new. Sports betting has been legal in most parts of the World for some time. Football data in Europe is so expensive, very good businesses like Opta can make a very nice living from it. Go get a quote for them for Premier League games alone: thousands a year for only some of the data.
For years, people getting into sports analytics have done so via baseball (and the Sabremetrics community), and the NBA because the data has not been seen of commercial utility. It's been collected by fans.
