Grand Colombier is a perfectly fine climb. It's just Culoz needs to stop paying for it, so we can use other sides. Unless we do something with the descent back into Culoz to keep only the steep part of that side, that would work. But nevertheless there is nothing inherently wrong with it. Yes, the tougher gradients are at the bottom and it gets easier higher up... but that's precisely what people like about Alpe d'Huez, and criticise about things like Bola del Mundo, Cuitu Negru, Puy de Dôme or Col de la Loze, where the final part being the steepest means that everybody waits for that part. However, Grand Colombier is also being used abysmally, and it is developing a reputation as, like, the anti-Formigal. Formigal is a nothingburger climb that has no right to produce entertaining racing and would ordinarily be the kind of stage where we see a sprint of the elites in the last kilometre or so, but seems to invariably produce far more than it offers; Grand Colombier is a climb that offers plenty and delivers nothing.
Kuss doing nothing is excusable because UAE were doing his job, but I really don't understand chasing down Adam Yates unless he just remembered that one part of his old job was to not just make sure he did nothing interesting, but to make sure nobody else did anything interesting either. UAE riding all day to gain nothing like they're prime Jumbo-for-Roglič? Well, since Jumbo have never been able to truly escape any inadequacies being labelled Rabofail, I don't see why we shouldn't call the effort expended for such paltry returns today Lamprefail.
