Australian Survivor removed from Paramount Plus as well as New Zealand and South Africa, I ponder why?

Luckily I was able to watch all 6 seasons of Australian Survivor, and was quite impressed. There are a number of positives of Australian Survivor over our US version, e.g., longer stay (50+ vs.39-), More twists, more players, more content, etc. I wonder if the popularity of Australian Survivor rattled the big wigs in CBS and made them worried about how much better that Australian Survivor is as compared to the US version. I am a huge fan of both US and Australian Survivor. I realize that Australian Survivor benefited years of US Survivor to learn from the shows. It seems that our Survivor is popular around the world!
