The frustration is understandable, server stuff will always gonna be a weird topic to talk about because of the points you mentioned.
The reason I made the post is that I've seen A LOT of comments that, based on the games history (since MP came out), are assuming pretty bad stuff which obviously isn't good.
From experience, if they go in with those assumptions, and the launch doesn't go "well", they further cement that mindset and hold on to it for a long time (even after the issues have been resolved), ultimately giving bad rep for the game.
An example is people saying blizzard are bad at launching their games. All because in 2012, more than a decade ago, the Diablo 3 servers was in a bad state for a while. It's kind of ridiculous.
In the end the important thing is that things are running as smoothly as they can.
