I heard this argument a few times when I bought my Volt, "Why are you buying one? They can't be that good if Chevy is discontinuing them". Thing is, when the Volt was killed, so were other GM cars, like the Impala. This wasn't necessarily a problem with the Volt itself, but likely a problem with cars. People are buying Crossovers and SUVs.
As for batteries, I have a buddy who is a big EV / renewable energies enthusiast who follows this stuff better than I do. A year or two ago he got all excited because he found that when EV batteries were no longer road worthy they could still be used in other applications. I'm not going to look around for info myself, but re-purposing EV batteries makes sense.

That was just one of the first results I got googling.
Experts are working on how to recycle EV batteries when they completely fail. Sure, it is expensive now, but that'll change as they learn more about it and then scale up the process.
I do like to think that I've reduced my carbon footprint with this car, but I've accepted that most of my power likely comes from a coal power plant. I figure that I've diversified my fuel source, I can run by solar, wind, coal, natural gas, so it frees up gasoline for the people who need it, because I don't need to be burning gasoline to go to the grocery store. I'll save the gasoline for the work vehicles, or the ones that are towing. I grew up on a farm, I still have family in production agriculture. Electric tractors aren't right around the corner.
I enjoy the free charging station at my grocery store, and I appreciate that I don't have to mess with gas pumps which is beneficial because I'm not buying near as much junk food as I used to (saving money and eating healthier) and I don't have to touch a potentially covid infected gasoline dispenser. I do an overwhelming majority of my charging in my garage, and public charger plug-ins are a lot easier to wipe off with a disinfecting wipe than gasoline dispensers.
And I'll look forward to installing solar panels at my house one day, so I can feel like I'm charging with clean solar energy.
