My crystal ball tells me that removing old.reddit.com will be Reddit's digg-v4 moment (that is if management doesn't dream up a reddit-v3 with the same original taste but more ads).
Any long time users of Reddit I will continue to welcome with open arms to their new home they may find in the Fediverse.
I watched five minutes. That, and the few minutes I'm taking to write this, is about all the time and mental capacity I can care to afford Reddit now.
I'm so glad to have places like Lemmy and Mastodon and the individual forums where I can exchange ideas with others. Reddit has become a pile of dung over the past five years. It's just full on nonsense and lies and rage bait. I was tired of calling people out for their misrepresentation of the facts and their twisting of the truth to fit their narrative. Although, I realize this is certainly not a Reddit-centric problem. It's just the place I hung out the most where I was most exposed to it.
Carcinization is an example of a phenomenon called convergent evolution, which is when different groups independently evolve the same traits. It's the same reason both bats and birds have wings. But intriguingly, the crab-like body plan has emerged many times among very closely related animals.
