Overbooking and oversubscription are inherently very different.
Flying is a one-time service with a specific and fixed point at which the service is provided. Its peak usage is the expected usage.
Internet access is a continuous service promise where it's nonsensical to expect the provider to predict exactly when every customer would want to use it. The peak usage is not the expected usage.

These are not comparable situations.
