Nope, Apple is not going to answer you by posting anything here and anyone that wants to have their concerns heard by Apple will use the Feedback link.
It seems like you think this is a Social Media site, but you are also wrong there, it is a Support Site for other Apple users like you to provide assistance for a Technical Support questions when possible. We don't speak for Apple and certainly have no obligation or care about defending any decision they have made. That is exactly the type of discussions that you would find on a Social Media site along with the rants and comments such as they are going to switch to another platform. No on here cares.
You have been given all the correct information whether you like it or not.
- Apple documents removal in group chats ONLY when there are 3 other people.
- The feedback link is used to submit feature requests.
- Why questions are not answerable by other users for any decision made by Apple that is not documented.
Whether you like that or not is up to you. What you do with that information is also up to you. It seems your other posts on this Support Site just follow the same pattern on how you are unhappy with Apple. OK noted, now what?
