Significato della licenza MIT

1. Puoi vendere il software.
2. No, non sei obbligato a fornire il codice sorgente.
3. Chiunque riceva il codice sorgente può fare come consentito dalla licenza. Questo non si estende alle distribuzioni binarie.

Leggi la licenza del MIT. Leggi tutto e comprendi. Doveva essere letto da gente comune, a differenza di altre licenze molto complesse:

In base a "Comprendere le licenze Open Source e Free Software" di Andrew M. St. Laurent :

These licenses, as applied to the original licensed code, allow that code to be used in proprietary software and do not require that open source versions of the code be dis- tributed. Code created under these licenses, or derived from such code, may go “closed” and developments can be made under that proprietary license, which are lost to the open source community. For the same reason, however, these licenses are very flexible and compatible with almost every form of open source license.

Come sempre, consulta un avvocato. Se questa libreria viene rilasciata usando rigorosamente la licenza MIT, allora:

(i) Sì, puoi vendere il tuo software purché tu includa la licenza MIT come parte del tuo prodotto. (ii) No, non devi condividere il tuo codice con la community, ma sarebbe bello. (iii) Sì, la rivendita è consentita.
