What are the differences between the options when accepting communication with hostile ships?

After much digging around, information was finally added to the Pirate wiki, and it does not appear there are any long term differences between them. It just a matter of how you fight or flee from the pirates

If the player wants to avoid a pirate attack after being detected, they can use their communicator to speak to the pirate ships before they attack. The player can choose to give their cargo or units to the pirates, attempt to bargain, or call for help if they have a defense chit.

Based on that information, this is what the 4 different options do

  1. Refuse: Initiates Combat
  2. Bargain: Pay pirates with units to simply go away
  3. Comply: Pay pirates with units, which is valued at the inventory they are trying to loot
  4. Alert Authorities: Initiates combat, and uses Defense Chit to call for help
