I know it's not your message, but I think it's related and it points to a deeper pattern: clicking on a folder in dolphin is essentially a link. On a web browser everyone is used to single click to open links, on a file manager it's unthinkable for many people.
My whole point is: what to you seems highly related, to other people might seem completely unrelated.
In this case the two interactions you cite are, for some, unrelated. Hence everything looks normal to them
@PseudoSpock @Bro666 I am just reading this as an outsider, but I can say that if the first message was something like "I hope this time features are going to be preserved. I still remember the transition from KDE 3, where I lost x, y and z" it would have sounded different than "watch this end up like the KDE 4 fiasco". In this second sentence I assume that your expectations are already set, for a bad release.
Now I'm genuinely curious: is something important to you being removed from Plasma 6?
