A long time ago, I had asked this question about whether a Battle Master fighter with Extra Attack can do a Commander's Strike after he throws a net. It got answered in the negative (you can't give something you can't take yourself).
However, a very interesting comment sprouted from it:
Can you forgo an attack to use Commander's Strike before throwing a net?
The Extra Attack feature states:
Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.
The description of the net's special weapon property states:
When you use an action, bonus action, or reaction to attack with a net, you can make only one attack regardless of the number of attacks you can normally make.
When you take the Attack action on your turn, you can forgo one of your attacks and use a bonus action to direct one of your companions to strike.
