Why did reddit get rid of r/all?

I know most will say they just use their home subs and just beef up mine, but I liked seeing posts from subs I've never heard of that were super interesting.

I tried r/popular and it sucks. Almost nothing I'm interested in pops up. The algorithms must be vastly different. Like 20% of the posts are Indian subs, nothing against them but I'm not really interested in their politics or understand their memes. I'd say like 1 out of 30 posts are something I'm interested in. In r/all it was WAY higher.
