They are not paid to entertain. They are paid to do a job, which is to work for the team.
Caceralla had to wait up otherwise his main man would be miles behind in the GC and could have possibly lost any chance of winning / top 3.
As for the non-sprinting at the end I initially thought it was boring but seeing that there was a petrol spill I think its justified. Alot of riders went down and got injured so a neutral finish imo was alrite.
Hopefully that is the end of it though and they just get on with it, if its a protest for today they shouldn't even enter the tour, if they cant ride on cobbles…well there not so pro are they!
