I'd never really thought about this before, but if there's a will there's a way. You could definitely see teams or fans using devices to try and prevent riders from winning particular races. Preventing gear shifting or even downshifting a rider, but you'd think they would just prevent them from shifting gears altogether as that would be the safest. If this does happen, I'd expect teams might opt for bring back electronic shifting but with cables, or they may go down the route of trying to add a level of security to the wireless comms. Imagine the Olympic games where a fan prevent a rider from winning. Luckily in the world of cycling there are only a around 2-3 major manufacturers of electronic shifting, therefore the effort to resolve this would be fairly concentrated.
