You sound personally involved. Your comment is the one being downvoted, because the hubris of "it works for me so everyone should be using it!" is absurd. The fact is many of the QR codes shown do not in fact work on many devices. Your use of all-caps also violates HN rules.
Judge proportional to downvotes, you miss great ideas, demonstrated in your thinking. The only hubris is your misrepresentation, and only absurdity? Your low-fact, untested 'fact'. Also, you hallucinated the all-caps. Hahahaha! :)
