I think people have different perspective than being "wrong".
I think its wrong to compare the sport to the past. You don't do it for any of sport do you? Footballers were (generalising) alcoholic, chain-smoking bludgers in comparison to todays professionals - do you compare them, or even can you compare?
Sport changes, cycling is no different. For me, any cycling is interesting, in all its new incarnations and you should ask Chavanel if he thinks breakways don't succeed in Grand Tours. Or De Gendt about Paris-Nice.
The UCI shouldn't be imposing new rules to liven up the racing and create more 'spectacles' for fans. If the pros for the riders and teams to have something like radios, which have become essential, far outweigh the cons then leave them.
New technology, new tactics, new riders, everything changes, lets not try to be bogged down by "glory days"
