I really don't know what "Forum Dad" really means, is it someone that feels compelled to tell others what do (regardless of their age) or someone who is believes in structure, procedure and order rather than the opposites of those terms?
What I do know is that there is a subset of individuals throughout the digital world that make insults/negative comments of all types to see what reactions they return. They bask in the glory of their notoriety and must derive some sort of self-satisfaction because they repeat this behavior over and over again. Also, it's easy to do.
Even your video is a response to their baiting. Unlikely that you or anyone will stop these individuals from doing what they do.
As to the docking computer, I stopped using it because the darn thing was trying to kill me, it wasn't to be trusted.
If some player has the CR to buy ship X, by all means, spend the money.
If they want to fly w/o re-buy or they get smoked by an NPC or another CMNDR and they post their complaints or experiences on the forum, they should expect a whole range of responses; sympathy, ridicule, insults, and maybe some helpful criticism.
"Blaze your own trail" is sometimes the explosion of your ship because you should have thought out what you were doing.
