The problem as I see it dv, is that you pose a perfectly reasonable question, to which none of us has the answer, and our non reply is seen as not wanting to acknowledge that you May be right or you may be wrong.
Continued speculation and hypothesising by yourself on this question doesn’t bring us any closer to the answer despite the volumous times you repeat yourself.
I acknowledge there would be a good or bad reason to change, but the reasons won’t ever be spelt out publicly, so may I suggest we move on.
TV on the other hand dug very deep and found snippets (or crumbs) of facts that were posted to try and help us all build our own assumptions. If you have any such snippets or facts please post them, don’t just speculate or guess as it is getting very tiring.
Cheers
