I have no interest in racing or anything UCI-related. But those rules are shaping bicycle design and stuff that is banned by the UCI will vanish from the market or be extremely expensive as it is totally niche. I would like to have some aero-attachements on my bike, but since they are banned, they are simply not available.
And let's be clear: At a certain level money can buy you victory. Show up with an expensive, state-of-the-art bike at your local race and you will have an advantage. You still need to produce the watts, but if the UCI really wants fairness, they need to standardize on a road bike for everyone with the same components and stats.
