This already happened a couple years ago. In the US or possibly the entire NA market, JJs stopped selling their original talc based formula. I did like you and rushed out to buy every last bottle i could find (I should have at least a decade or twos worth of powder now).
However, I was shopping online for it too, and discovered that in other markets outside the US, original talc formula and even other scents using talc are still being sold. You can find international listings on eBay and Amazon.
About what happened. Everything I've read has led me to believe they discontinued US sales for political reasons. The story goes that ppl(mainly just females) are prone to some cancer caused by asbestos that is naturally occurring in talcum powder. During manufacturing JJs has measures in place to get rid of or mitigate the asbestos contamination. Research and analysis was done. Though not present in all or even the majority of bottles, trace amounts of asbestos have been found in JJ talcum powders sold on store shelves. But, despite those findings, it has never been clearly linked to any cases or rise in cases of cancer. Lawsuits were taken out against JJ but I don't think anything ever came from them. Legally they were still allowed to sell talc based products, and were...until the pandemic. Public boycotts and bad publicity came to a head and at the start of the pandemic talc products were no longer profitable for JJs in the US, so they discontinued sales in US markets.
I'm hoping that one day the world comes back to its senses and we can all have talc in stock at our local stores again. It has many uses beyond just diapering(I used some to locate a transmission leak). I've yet to try anything that comes close to the feeling of real talc, and yes it just works better. The texture of it is heavenly. CS powders can feel gritty and actually support bacterial growth.
