Its irrational to make some of these broad conclusions based on one persons winning streak. Thinking that books have changed their approaches in spread making or that books "prefer sharp money" over public money is not logical at all, guys. Your bud is just on a hot streak, whether its due to variance or some other factor (like more researching for example), thats all it is. Sportsbooks (and every single other business in the world) don't care whether the money they make is from the sharpest gambler in the history of sports betting or some junkie degenerate, more money is more money. Sportsbooks will continue to profit in the longterm as long as they have vigorish on their side.
