I have to believe that one or more of the following three things are true: 1) these people are paid to be here, 2) Bitcoin threatens their very manner of existence in some way, or 3) these people operate with a totally different set of values than the rest of us.
You missed one...
4) Some people who were interested in Bitcoin have seen it attract crowds of gullible fucking lunatics who queue up to be scammed again and again and again. They tried pointing out the stupidity, wishful thinking and maybe even predicted some of the incessant chain of cluster-fucks that more-or-less defines the "bitcoin ecosystem". About the only thing left to do is try and get a laugh out of it.
So, since a few intellectually impaired people have been scammed out of their bitcoins, you've launched a vendetta against bitcoin?
