Actually I thought the article was very fair and the authour went to great lengths to make it equitable.
As a long-time user of fenestrons on Gazelle and AS 365 (instructing on both) there is definitely a different feel to one over a conventional TR but both work equally well - just requiring s subtly different technique.
It sounds like the GA (H) community are revisiting what was referred to as Fenestron Stall in the UK Military 30 years ago on the Gazelle - it was lack of sufficient right pedal then and it seems to be the same now on the Cabri.
Think of it like Nr control in auto - a small input made pre-emptively avoids a larger input required reactively - just a question of anticipation.
