To clarify, the Rules specifically state that ramming with a head start from across the field is illegal. As are strategies aimed solely at the destruction or disablement of other robots. As Ken says, pushing and very limited ramming are allowed solely to gain a positional advantage on the field. You must be trying to get somewhere or keep someone from getting somewhere, not attacking their robot. The only leeway given on the ramp is with respect to pinning.

Even a cursory glance at the rules makes this clear, so I'm uncertain where you got the impression that this is a "free-for-all".
