The counter-argument would be that fouls themselves are not fun to watch, and giving defenders any reason to foul more often is a net negative for the game. This does not pass the smell test, however, since the foul shot is so efficient that even a slight nerf to its effectiveness would not come close to making that a "good" outcome for the defense. The league shot 76.6 percent from the line last season. Knock that down by a few points (or by ten points!) and the offense still comes out on top. The league would have to shoot under 55 percent on free throws to underperform the median offense from last season.
