急求翻译：It is not so much a license to operate as a license to

急求翻译：It is not so much a license to operate as a license to obfuscate.这是关于社会责任三重底线报告的评价.全段是：The great virtue of the single bottom line is that it holds managers to account for something. The triple-bottom line does not. It is not so much a license to operate as a license to obfuscate.我对此的翻译为：单一底线的最大优点在于它能让管理人员各负其责。三重底线却无法做到。但最后一句，我知道是这与其说……不如说是……的句型，但可翻译上不知道怎么处理。请高手帮忙，找出最佳翻译！
