I don't see many people mentioning what to me is the largest cause of slow internet. A weak WiFi or 5G signal caused by being behind a brick wall or far away from the router.

This is the only reason I know why some websites/apps perform poorly on a bad connection (Discord struggles simply load the text content of messages).

Another one is being at a huge event with thousands of people trying to use mobile data at the same time.

If nothing else I think these two cases are enough to motivate caring a little bit about poor connections. Honestly I find them more motivating than developing for whatever % of users have a bad connection all the time.
