I think part of it is that some of us are not used to reading (or writing) praise, apart from seeing the over-praising of LLMs, such that seeing praise in the wild makes us think of LLMs. This being used to lack of praise is partly reinforced by certain tech cultures (e.g. keeping ego out of code review, this implies not wasting time on personal praise/criticism but keeping remarks focused on the technical, and keeping in mind the distinction between technical and non-technical critique).
