In general, I suspect you'll see more paid streaming services bow out. The reason many people originally "cut the cord" and got rid of cable and dish subscriptions was to save money. They bought an antenna to pick up no-cost OTA content, and a lot of past episodes of TV shows and series, movies and live sports programming could be found online for free, or certainly much cheaper than a monthly cable subscription in many cases, depending on what one watched.
Now that many networks like Discovery, ESPN, NBC and others have moved once free content to their paid streaming services, and in some cases sporting events, series and original programming can't be seen on cable and is only available via paid streaming, many folks are being selective as to which services they'll pay for and subscribe to. Those streaming services obviously cost $$ to operate, content generation and equipment/staffing cost $$, etc. so if they don't have enough paid subscriptions to make a solid go of it, I see more of them bowing out or changing their model or approach.
Regarding CNN+ in particular, I personally wouldn't be interested in paid streaming from any news outlet. There are plenty of news sources available otherwise (I think I have probably a dozen news apps on my phone, for instance and none require a subscription) and If I'm interested in more info about a specific news item or story, I generally use an aggregator to get detailed stories from a number of online sources. Also, I personally prefer to read the news rather than listen to a podcast or watch a video, with certain exceptions.
