Speaking for myself, I wasn’t intending to “jump all over [you]” for this. You were just the lucky person who made a comment about poor performance in a beta thread.
As I said then, I get the frustration, but some of the issues I, at least, have is that there is a lot of complaining about the performance during betas. We all know there are issues. Moreover, Apple knows there are issues! They are betas. They exist to resolve issues!
In a beta thread, it might be better to just note the issue and not add commentary about (A) how Apple can’t do anything right anymore, (B) the software sucks (C) If Steve Jobs were alive, all would be right with the world, (D) etc....
In threads about released products, throw out (most) everything I just said about betas: released products are supposed to work and clearly iOS 13 has not lived up to that standard. By all means complain away on a release version thread!
