>If you honestly don’t care at all, use the WTFPL (the Do What The Fuck You Want To Public License).
Unless you don't want the legally risk-averse to avoid your code, in which case you use the CC0, which is the best fit to put your code into the public domain.
it might be because usage has picked up in the ~7 years since this article came out, but the Apache license is seen more and more frequently, and I think that it's definitely a better alternative to the MIT license given that it has a patent grant clause which is increasingly more important.
Also, the MPL is an interesting alternative to GPL, although it's definitely not pervasive and it's a little bit of a bastard child of the LGPL and MIT licenses.
It's probably one of the most common licences used on Android (and considering that most apps use AppCompat - an Apache licensed project - most apps have to be Apache or GPL3 legally)
