I personally accept the fact that some developers would like to use weak copyleft or strong copyleft licences for their works. However, I still prefer to use the MIT X11 Licence for works that I originate and now I’d like to explain why:
The MIT X11 Licence is short, simple, and easy to understand.
It is practically public domain which is what people innocently expect when they hear terms like “open-source” or “free-as-in-speech software”.
By using such permissive licences, one has much fewer worries on how people can violate one’s licence. While I commonly hear about GPL violations, I don’t ever recall hearing about a violation of a permissive, BSD-style licence.
The MIT X11 licence still gives one protection against litigation with its “NO WARRANTY” clause.
The MIT X11 licence is GPL-compatible, so it can be made useful to people who are using the GPL.
By using such a licence one can boast that one’s program is Public Domain / BSD-style-licensed.
