Well, I think literally everybody involved should be embarrassed and ashamed of themselves for that pathetic show.
Maybe Kuss shouldn't be ashamed of himself, but he should be embarrassed that such a pathetic show of passivity is the only reason he's winning a Grand Tour.
The Jumbo team brass should be ashamed of themselves for letting Twitter decide their strategy for them because they're so scared of negative PR that they can be bullied into doing whatever a bunch of people who follow Jonathan Vaughters unironically want.
Jonas and Primož should be ashamed of themselves for being so weak they accept such instructions and perform their act so transparently fakely.
Movistar, UAE and Bahrain should all be ashamed of themselves for being so caught up in battling over minor places that they did Jumbo's work for them half the day, sitting in idle passivity and letting this absolute dog and pony show take place, while then taking up the pace on the last climb to avoid Jumbo having to make any decisions.
The race organisers should all be ashamed of themselves for allowing a third significant stage to be neutralised.
