That wasn't really the issue with this though. The issue is that CNN's audience is OLD (roughly around 55+ on average, I believe it might be closer to 60). All other networks have old audiences too, btw. It's been proven that there are a lot of older viewers who are very hesitant to switch to streaming. Young audiences don't watch cable news. They watch youtube or catch clips here or there for news, which is another reason this was and entirely unnecessary streaming service.
If CNN was going away on linear cable, I could see why this might have more of a use factor, but CNN is still putting out more relevant content than CNN+ ever will. So in the end who was their audience here? I'm really not quite sure.
Once Discovery+ merges with HBO Max, a CNN live section is very doable. No need for special "CNN+" crap, just give CNN's library of films and documentaries along with a tab on the side that lets you watch the linear network live, included in the subscription (similar to how Paramount plus gives access to your local CBS station).
