Now, you can accept that as a valid criticism of your attitude and think: I should lighten up a bit and not expect serious involvement of end users in my pet project (although I doubt you significantly contributed to LibreOffice). In that case, why the passive-aggressive tone? Why not accept that end users expect that a released product has at least seen a moderate amount of testing and that kamapuaa's expectations were quite reasonable?
Or you can think: how dare that f***ing bastard suggest that I was wrong! In that case, you're the problem.
