I do agree that it's not really a duplicate; but it should remain closed.
For one thing, it's hard to understand the question behind the huge rant. Your rant seems to entirely focus on how unclear some people are when they discuss the "number of atoms in the universe". From what I've understood, you seem to have an issue with how some people choose to explain the estimates for the number of atoms in the observable universe. I can see how this led people to close it as a duplicate; your question wasn't exactly clear with what it was trying to ask.
The question seems to mostly concern itself with the wording of people saying "the number of atoms in the universe"; when really they are estimating the number of atoms in the observable universe (not estimating the number of atoms that could fit into the observable universe). Although I think it's useful to make this distinction between the universe and the observable universe, I don't think the question is on topic for this site.
It seems like a primarily opinion based question, based on your dislike for current explanations of that estimate. I personally also don't really see the issues that you see with the explanations, so that especially leads me to consider it opinion based.
