There's an argument to be made that it's all been captured in the internet archive, but I still think that reddit gets most of its value from active users, not drivebys looking at posts from a decade ago. I'd rather those vital parts of internet history be findable in their original, SEO captured location, but I also understand the reasoning behind getting rid of all that and moving it strictly into internet archives. The thing is, the 2010s have taught us that the addage "once it's on the internet it's there forever" is patently false. The internet has turned out to be incredibly fragile with big chunks of history that wasn't archived going away forever. Our collective memories have been edited by companies going out of business and deleting all their cloud storage to avoid incurring further cost.
