Ironically, it seems this clone does a great job of cloning the performance of reddit, at least when I tried it (bunch of unnecessary requests that takes multiple seconds each, sometimes just returning errors)
I had an internet outage that left me with a few kilobytes/s upstream/downstream. Most of the modern web was plainly unusable, often requests got terminated before all data was transmitted.
But reddit among few other sites did work quite well. Of course not for pictures and media, but the text and comments were quickly displayed. In hindsight I am not sure if that was better than a complete outage, but that is a content problem.
If they take that away, I will kill my account. My account is 15 years old on Reddit, with near daily use.
