That’s a traffic shaping problem, not really on the person or service. Streaming would be a better example because that’s immediate and you care about uploading in a timely fashion and best quality, but if you limit your upload bandwidth you can manage it better…
But then again we’re talking about upload, in general, upload only matters in a few situations, latency will be more important, and download is always more noticeable than upload speeds.
Even doing making youtube videos the only reason you need instant fast video upload is if you’re trying to push drama videos, and even then, I’m probably fine with them being slightly limited by that. But ultimately uploading videos is only slightly inconvenient for modern broadband, if it’s that bad, look into how to limit how much bandwidth it takes up, there’s good ways.
