That's pretty much the entire point of a thin client. If you've got a device with, as the user said, "limited network bandwidth", then downloading hundreds of megabytes or even gigabytes of Docker images or npm packages or whatever within a reasonable amount of time might not be doable but streaming at 10 Mbps might.

You still need enough bandwidth to stream the video. That is not up for debate. Their servers do not magically mean you can stream things from their servers to your client as if you had a fast internet connection if you do not.

Nobody is arguing that they did. The point is that you don't stream things from the server that require a fast internet connection, just video of the server.
