I'm confused by the comments that seem to imply that the author is taking credit for ideas that they're writing about, as I didn't get that impression from writing in the article at all.
I'm also confused by the idea that they didn't provide enough citations for concepts in a non-academic source. I feel like in the day and age of Wikipedia it should be sufficient to colourize / bold terms like "Entropy coders" or "Huffman Encoding" to indicate to the reader that these are important terms that they can research for more details if interested.
Overall I guess my position on this is that ~80/285 comments on this post are related to whether not this is a good post which I think is far too many. There are slight issues with the post but they aren't worth 80 comments.
