Hate to burst your bubble, but volunteer time is something important to loads of other industries as well.
HR isn't hiring you to just be a good pilot, they also want you to be a good employee. *gasp* How horrible.
If you don't understand why volunteerism is a criteria that is valued, instead of raging against the system like a 12 y/o angry at his dad maybe you can look into why companies have this practice.
I can guarantee you it has little to do with pandering to a millennial's social justice leanings.
