Global South basically just means underdeveloped/developing nations.
Capitalism results in the rich, mostly in developed countries, extracting resources for low prices and exploiting desperate workers for low wages in developing countries. The developing countries get little in return. Some of these countries have been able to muster some protectionism to mitigate so much transfer of wealth out if their country (such as China). Developed nations have purposely kept some developing nations destabilised to maximize exploitation.
Yeah, I’ve been experimenting with YaCy, and discovered they have a PageRank-like algorithm, but it uses a lot of resources, so they don’t recommend using it and it’s turned off by default. Haven’t tried turning it on myself. Looks like the maintainer is focusing on YaCy Grid, meant for organizations, not general decentralized search.
