Is this exploitation or good business ideas?

A group of Black Americans from ATL realized many ppl in The Gambia never heard of silent disco, (each person get a headphone and two dj play diff music that goes to the headphones, so everyone on dance floor is dancing to something diff) so the Atl opened one over there & is making $$$$$. They made sure their entire staff is locals from the Gambia to bring jobs and not just take away.

An African immigrant who grew up in USA , moved to Angola, said ppl there didn't have PayPal, so he made up a knock off PayPal and put it over there & is making $$$$$$$$$$$$$$$

I thought this was a great idea, that would bring money to both those on the continent as well as money to others in diaspora , however some ppl said, no it's just exploiting ppl overseas and forcing capitalism . Thoughts
