I can not agree with applicability of that aphorism in this case.
We have had a very vocal feedback loop of raising issues ("stupidity", "misunderstandings", "neglect") with OP conference as one type of such feedback.
Nothing has been corrected. Do you happen to know of another aphorism that covers the "willful stupidity", "willful neglect" etc. and what it all means (as I certainly don't desire hitting London.)
Obviously those with their hands on the production pipeline of tech disagree with the feedback. Is that really a controversial observation? Really?
