Infinite times. The group of people on the forums tomorrow will never be the same group as today, and one of the new group members will bring with them some anxiety or dislike or confusion over addons. It's literally impossible to eradicate confusion over this stuff.
We can't even do it in the real world when it comes to the shape of our planet. There will always be someone new to Earth who, unfortunately and for whatever reason, just doesn't understand how things really are. It's futile to think we will ever be done explaining reality to other humans.
