If you are unhappy with the terms or products of a company, you are free to shop or work elsewhere. That is the difference. "Capture of surplus" is hate speech - without those companies, there would be no surplus to begin with, that anybody could capture.
If you believe those companies will capture so much surplus, you could also buy some of their stock and participate.
Nothing against educating girls, but this is probably the wrong conclusion. Economic situation determines whether girls can get an education or not, so educated girls correlate with a good economic situation. Not the other way round (educated girls causing a good economic situation).
Personally, I think this focus on girls only is sexist and I take care to never donate to charities that only want to help girls.
