Not sure about the US and not a lawyer, but often as a founder/board member you sign a shareholder agreement which includes a provision not to undertake anything which would deliberately cause damage to the company/other shareholders. There are perhaps other points as well. I imagine the US is more litigious here than Europe (where my experience comes from)
