I'm a bit confused.
Guillen said:
"“We knew that there would be rain, but not that nature would have a blackout,” he insisted. “I can understand the riders’ criticisms in the sense that we were expecting something different. We are the first in line to hope things play out differently."
so he admitted things didn't go as they thought they would, and I read between the lines that he agrees the circumstances where not OK. Ofcourse he doesn't say out loud that this is his responsability (he stresses he consulted 3 weather forecasts, already moved it 20 minutes and wasn't able to move it more due to big city planning). But yes, he admitted it was not good.
next, Guillen spoke with riders after his initial proposal to take times with 3K to go (on top of Montjuic):
“There’s a formula for these circumstances, the extreme weather protocol, which we used, and this morning the petition came through to suspend part of the course because of the very heavy rain and its effects,” Guillén said.
After he spoke, riders and organiser agreed on taking times at 9K to go. So yes, the riders were listened to, if only after guys like Remco complained about the initial proposal and after Vingegaard said that the organisation doesn't listen.
so in the end, yes, the riders were listened to.
