Waton,
I understand what you’re saying but I believe most of these new partakers are partaking DESPITE WT teachings and not in support of them.
Already the number of partakers has grown so much that it has forced WT to abandon their teaching that the number should be dwindling as a sign of the closeness of the end. And WT was teaching that as late as the early 2000s.
These partakers are not concerned with WT rules or 144,000 theology. They are simply making their faith publicly known.
And yes, there are many MORE who partake privately at home. I also know some of these people.
