While "less freedom" does tend to sell better (*cough* Call of Duty *cough* wheter it makes better games is very questionable. After all, how good is Deus Ex? How much freedom does it give the player? There's your counterpoint, no big article needed...
Deus ex
1. Had an excellent tutorial.
2. Every strategy was viable at all times with minimal investment of resources. Just pick up a gun or an aug or invest a couple thousand points.
3. Made most strategies simple to carry out and obvious. You want to sneak around? Crouch and don't let enemies see you. You want to blow enemies up? Pick up grenades and throw them at them.
4. Put overwhelming power in the player's hands from step one. With a gep gun you can kill any enemy in the game untrained with two hits, and most groups. With a sniper rifle you can kill 90% of the enemies in the game with one headshot untrained.
WMOTA
1. Laughs in the face of tutorials.
2. Requires ten or twenty turns or more and new cities to set up any new strategy.
3. Requires great effort and great understanding of the game's innermost workings to set up any strategy.
4. Gives you little to no power early on.
The difference is in deus ex freedom doesn't matter and in warlock freedom matters. In human revolution where choice did matter due to the boss, people got annoyed.

Choices are ok as long as none of them are wrong.
