This issue has been discussed at length, but I have been unable to find a definitive answer.
Very simply - does throwing a net require two hands, or can it be done with only one?
Evidence for one hand: CRB, pg. 202:

Thrown Weapons: The same rules apply when you throw a weapon from each hand. Treat a dart or shuriken as a light weapon when used in this manner, and treat a bolas, javelin, net, or sling as a one-handed weapon.

Net and Trident (Combat)
Your skill with lighter weapons allows you to wield one alongside your net.
Prerequisite: Dex 15, Exotic Weapon Proficiency (net), Net Adept, Two-Weapon Fighting.
Benefit: You can treat a net as a one-handed ranged weapon, allowing you to wield a light or one-handed melee weapon and still make ranged attacks with your net. When you use your light or one-handed melee weapon to attack an entangled opponent, you gain a +2 bonus on damage rolls and on attack rolls to confirm a critical hit.
Normal: A net is a two-handed ranged weapon.
