I admit I don't have ground truth here, but the whole thing reads to me as very clearly AI generated. For what it's worth, Pangram agrees. In my view, this style of blog post does not "prioritise people and community" as "Generated text should not be relayed as a substitute for the contributor’s own judgement".

When the content is AI-generated, it's very hard to suss out what, if any, human judgement was involved.
