Al contrario, la licenza MIT non richiede il disclaimer in garanzia da conservare in tutte le copie del software e solo gli "AUTORI O DIRITTI DEL COPYRIGHT" sono protetti dalla responsabilità per danni.
Sembra che la licenza del software Boost offra una migliore protezione contro le responsabilità di chiunque si occupi del software (anche quelli che stanno semplicemente distribuendo il software). Inoltre, la licenza del software Boost rende obbligatorio riprodurre il disclaimer in tutte le copie.
Perché quindi l'autore della licenza Boost menziona in link che la licenza Boost "non estende la liberatoria di garanzie ai licenziatari, in modo che possano, se lo desiderano, effettuare tali garanzie (ad esempio, in cambio di un pagamento)" ?
