My guess, break existing old links on other sites so that they can show a graph with a drop in usage of less-ad-riddled way to access the website and drive more to the ad enabled views.
I love the two comments calling out that this thread was posted to the help subreddit rather than any of the other more appropriate subs for changelogs.
They have already been trying to bully old.reddit users for quite some time by forcing a regular cookie acceptance prompt which automatically changes the settings to new reddit.
Tbh these really are low-usage features, I didn't know about any of them, aside from the snoovatars that I've always found stupid. So I don't think anyone could be pushed away from the site because of this.
OTOH, if they're low-usage, why remove them? Do they spend too much bandwidth, CPU, whatever??
Another day, another disappointment from Reddit. I deleted my account the day you made your instance and thankfully things over here picked up pretty fast. I haven't felt a need to go back.
tbh if you need to see a reddit post use a frontend like redlib it doesn't have signing in with a reddit account but atleast you can browse a post without tracking
They've already outlined their general plan for removing old.reddit. It was buried in the middle of an announcement post like 2 years ago. It's just a matter of time and usage at this point. This is probably a slow creep method.
It's sad to see something so much time has been dedicated to, become shit. I guess it was like building sandcastles, afterall.
