This hn thread is a perfect example of a news bubble. Googling "fbclid" returns the answer in the first result, but hn votes up an article that has no information and treats it as some secret tracking that fb has implemented. HN is excessively biased against any discussion of tracking/analytics on the internet. The community allows no room for true discussion - only blatantly biased opinions.
