They cannot for now, old.reddit still drives a LOT of traffic for them and most of the reddit oldheads from what ive seen just use old reddit to surf the site, so if they're not stupid enough to drive a huge part of their userbase away from their shithole to sites like lemmy and turn into digg 2.0, I don't see old reddit dying for awhile but remember this is spez we're talking about in the end, the self proclaimed Elon fanboi, so I cannot expect any intelligent decision from him.
Why censor the word "discord"?
