if the bread tastes funny then yeah i guess you as a customer have every right to talk to the baker directly since you've paid for it
No. You contact someone with higher authority tasked to look into such matters - this is how a business works.
The same for this game, you cannot go complain to backend and demand answers - they will not be able to help you because game design is not in their control.
You go to frontend customer relations for information - the people tasked to handle such queries. Such as this forum, or in-game support.
why would they listen to our feedback if they don't even listen to feedback from beta players?
For the same reason that a plan for the game has already been laid out which they are reluctant to share with you until closer to the time of release. As it's always been, we are only provided with information just before release dates.
If something is not working as intended, they develop on the feature or change a few things - they are not obligated to share this information with you nor are players entitled to demand the information. It will be provided at the right time when they feel it is necessary.
This game does not belong to you, you are happily provided the opportunity to make use of the services provided. But that's as far as your authority goes.
