Hedge funds seem to automate things in an environment where certain bugs are existentially threatening. They hire doctors of math and get their code correct. It's not impossible, just expensive.
I'm not going to comment on moral or legal responsibilities of bookies and gambling companies, because I am uneducated on both subjects, but I found your use of the term "collect more juice" really interesting. It seems odd to relate pulling revenue from fruit to pulling revenue from people's incorrect bets. Is that an industry term?
I think most sports betting consumers here prefer the current, lower cost, more diverse system with a slightly higher error rate.
I'd reckon most people complaining here don't even bet on sports, but want to grandstand against bookies. I can understand that I guess.
