I think there's 2 factors at play.
Riders wanna blame the course, or blame literally anything because it's an scary idea that it was just a rider making a mistake combined with the worst possible luck.
The organisation just wants to get this *** over with and is making any "compromise" it can to look like it's taking care of rider safety now.
The first part is IMO completely wrong. Riders are not wildly throwing blame around. They are mostly shocked and are not sure what to do.
The organization wants to finish it, sure.
The weird 25km GC time, continue for stage. The way Senn explained it, it's understandeable. Make sure all the riders are comfortable, those that don't want the stress in the final, high pace, bigger risk of crashes, don't need to be involved there. Makes sort of sense.
Obviously riders will feel more stressed, less sure than usual today (and for a while) The risk of something happening today if it's raced full power as usual is not bigger than in any other race, BUT riders (some) will feel more apprehensive than usual, the risk that is always there is more present in their mind right now, having to an intense final, having to stay in front because of possible crashes, splits, would be more stressful for them than it usually is. So give them the possibility to have another day off in the final, not to stress them out even more.
There's no right solution anyway, this one with Senn's explanation, cut the most stressful part from the stage, for the mental well-being of the riders, actually isn't as bad as I first thought...
Now of course it's up to the riders if they want to race or not, but I imagine riding a whole day at 25 km/h brooding over Mäder won't really help them, so hope they will make it a race.
