Earlier quoted context omitted.
I'd say it isn't in the US though, at least there's precedent that makes me think that: https://en.m.wikipedia.org/wiki/National_Basketball_Ass%27n_...
I think you misunderstand that case "compiled its scores and statistics by employing people to listen or watch the games, then enter the scores on the computer which transmits the scores to STATS' on-line service, to be sent out to anyone using a SportsTrax pager.[1]" Notice how they watched the game and got the statistics like that. The restrictions are about using the scoreboard and the data displays and reselling/…
I'm not a lawyer, but my interpretation of the lawsuit based on the Wikipedia article is that game results/scores are public facts and hence not copyrightable data. I don't see how the method by which that public data is collected changes anything materially about that case. Are you saying that inferring the score based on the scoreboard is what makes this illegal (why?)? What if they would infer the score using motion/ball tracking instead?
