I have a nice job. I wear a tie every day. People call me "sir" - even people decades older than me do this.
I don't want to log on for an event at 9 EST. I'm in the Central timezone, so this would be 8 CST for me. I want to have a nice late dinner, I prefer to eat later. I want to relax a few hours for eating, maybe read or play a flat game for a bit while I listen to music and rest my feet. After a bit of rest, then I feel like putting my VR headset on and socializing a little bit. 11 EST is a nice agreeable time for me. It seems that most NA people also enjoy living this way. I can't imagine that I would show up if I lived in the Pacific time zone, 6 PM is much too early. That's before I've even had my dinner.
Seeing as this is a long-running event and that the EU event will still be going at your preferred time, why are you so upset over this? Do you really feel that people like myself should be forced to log on early just because you want it to be that way?

I tell you what, you can have your 9 EST event. I'll just come along and host a separate one at 11 EST, which is the time that I prefer.
