There are at least 3 distinct reasons to ban abusive language, each of which is far more compelling than your silly conspiracy theory.
1. They don't want abusive behavior included in their training corpus
2. Humans shouldn't exercise abusive impulses in general
3. We have no way of knowing when or if a model "feels" something
Of course item (2) is going to pull all the absolute sickos out of the woodwork who apparently find it very important they have as realistic a facsimile of a victim as they can find to exercise their cruelty. And item (3) will pull out all the Nobel-prize-winners-to-be who somehow know for a fact that models aren't and cannot be conscious (or moral patients).
But yeah, all 3 of those are far better explanations than some ridiculous multi-hop removed thing to escape consequences that they're already escaping and which would obviously create far worse legal constraints than the one you think they're avoiding.
