> not that you can't use higher bitrate elsewhere

If, as a user, I think the video quality on another platform is superior to that on Twitch and knew that there was an alternative platform where I could watch the same thing at higher quality, the experience on Twitch is clearly less than that on the other platform. This breaches the first guideline.

> The second bit simply says "third party service"

And this is the real point: it simply says. It doesn't clearly specify, there is no definition of these terms. These vaguely/innocently worded hints will be enforced opaquely whenever they feel like it, without explanation of what, specifically, you did wrong.
