Why all proceeds from Elon and Mark goes to Veterans?

Aren’t they building global apps for global audiences? Why would they be so biased towards the US? Why would we, those outside from US even care about American Veterans?

Please American friends don’t get mad at me, just understand my point. I do have respect that you value your veterans and it’s all fine if you want to use money to help/support. Everybody is free to do it

I’m just pointing to the fact that if you manage global apps and pretend to welcome diversity, etc etc.. then using funds collected from adds generated by your global audience to fund American US Veterans sounds ridiculous
