Eh, in the past (maybe 5 years or more) THP was a lot fiddlier IME, and occasionally would hit bizarre cliffs in latency and overall performance. A lot of that has gone away. But because of that (among other things) you'd occasionally see advice like "Turn it off for <xyz particular workload>" so it sort of got carried forward to where people just generally disabled it.
