Hmm, it's pretty crap not to mention where the overwhelming majority of the code was clearly taken from – given they wrote a diary documenting how 'they' built this project, and then posted it on HN. And it's not 'inspired by' the other project. Lots of the HTML seems to have been copied verbatim into a React project, with very specific long CSS strings from the original site. Hilariously, even the tiny 'Inspired by' section at the end is itself stolen from the original site, which credits another site as inspiration (that site is genuinely different, emulating MS Word rather than VS Code). It was very courteous of u/pieterhg to respond the way he did, put it that way. ("Even still says index.php!")
