Kreia couldn't care less about the beggar. The point of her lecture was to get you to consider the unintended consequences of your actions, since she was screwed over multiple times by her own. That's why she says something no matter what you choose.
Kreia is a teacher before anything else. She's also a massive hypocrite, which makes her infuriating if you don't recognize it's intentional.
I believe the Restored Content mod restores some scenes where you can actually earn her approval (including during the end game), which helps a lot.
If Valve's Employee Handbook is to be believed, they don't use a formal project structure with static teams. Instead each developer works on whatever project interests them, and one of Valve's current goals is to improve game performance on Linux/AMD by contributing to upstream open source projects.
Valve is as close as we've gotten to someone paying a bunch of industry veterans to contribute to open source. It's amazing what happens when all innovation isn't black-boxed in an internal repository and forgotten about.
