Also note that the FSF recommends CC0 over the Unlicense if you want to release something into the public domain, but in practice the difference probably doesn't matter.
For that reason some corporations (such as Google) may restrict employees contributing to those projects, or utilizing those projects in any way.
MIT requires attribution which some like for their work as public domain means someone may copy-paste your work and present it for their own.
