If you watched the game, then you'd know that the Bucks are 30th in the league at getting to the line. Bogut was in early foul trouble, so they had no interior presence at all. They fired jumper after jumper last night.
LeBron took 10 FTs in the first half, and 4 in the second. Only TWO of those FTs came in the 4th quarter, with 7:31 remaining in the game. The Cavs also closed the game by making one FG in the last 6 minutes. This doesn't exactly bode well for your argument that the refs were "cheating" last night.
Nice try, though.
