Let's consider something here. Streaming services like Youtube and Netflix all deliver content in multithread streams - even though their CDNs are located as close to clients as possible (eliminating TCP latency issues)... If you want realtime streaming, multithread TCP is the only way to make sure it's reliable and that it works. Or ask RD to bring a server to SA and feed the Southern Hemisphere - hell ISPs are working tirelessly to bring services as close to you as possible which is why Google, Netflix, Facebook, Amazon, Cloudflare, Akamai, Apple, Microsoft and many many more are here. But the internet is not homogenous throughout the world, distance does matter - aside from the fact that distance costs real money. RD is taking your money to deliver a service, why not ask them to make it better?
