I think it's necessary to criticize technical work (or any work) as long as the people involved care about achieving good results and making things work. Agree

I think it's necessary to criticize technical work (or any work) as long as the people involved care about achieving good results and making things work. Agreed that we should not be excessively abrasive, and I think the facebook post is leaning that way - but I don't think a world without criticism can work - at a certain point in any field you have to face reality, in which some things work and some don't, and to protect every person involved from "emotional repercussions" is impossible because generally people's beliefs and feelings are all over the map. At any rate I'm not sure the author of LD_PRELOAD or ELF dynamic symbol interposition is scanning this thread - and after ~30 years distance might have different opinions about them, or at least a thicker skin :)
