The key phrase here seems to be:

well, think about it yourself: with a "not very good" internet connection, streaming, for example, at a quality of 200-300 kbps without loss, or using TeamViewer, where the more people connect, the more the internet channel is strained. And, consequently, the worse it is for all viewers.
+ there's also the idea that a large distance = a large ping. And a large ping affects the quality of the picture. Remember when Maretti streamed through TV? It was impossible to watch. Although I don't think he has such a bad internet connection.
