In a three way chat between the movement, politicians and the game industry, you need to know the technical details to rebuke the arguments and support your claims.

Also, the technical decisions are not just about saving a buck but getting the game shipped. If my game is about growing vegetables and I want to let the player drive to the state farm, but I don't want to spend time (and money) building my own physics engine for driving, I grab a solution off the shelve with their license and go back to the core of my game, this same thing is repeat for many other things like authentication, anti-cheat, networking, etc
