But a much easier argument against sports betting is that it ruins the sports. Players throw. They get good at subtly cheating. The gambling apparatus latches itself to the sport, to the teams and players, the umpires and judges, the sporting organizations. With this much money on the line, it's not a matter of if but when games are thrown, cheated -- the bigger the game, the bigger the incentive. It's even easier now because of the amount of side/parlay betting that is available. It exhausts the spirit of competition.
Sports gambling is diametrically opposed to sport itself.
For example, this ad https://www.youtube.com/watch?v=t0-pKS_zx5E is made by "LOTTO 6aus49", which is "LOTTO.de", which is "Toto-Lotto Niedersachsen GmbH", which is the lottery company of the state Lower Saxony.
To me this is as if the state would place TV ads for wine which a state-owned winery produces, like "Landesbetrieb Hessische Staatsweingüter" also known as "Hessische Staatsweingüter GmbH Kloster Eberbach".
And the lottery numbers are then presented in the prime time news in the publicly funded television.
Lotto and sports betting in its modern incarnation are very different.
Lotto was created so that people’s desire for gambling is diverted towards charity.
