I like publishing my software completely open source with no limitations (no contribution required, etc). I thought about using the WTFPL, but it lacks an MIT-like disclaimer:
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
I would really like to merge the WTFPL with the upper part of the MIT license so I have a license as permissive as the WTFPL but also with a disclaimer that I am not responsible for any use of it. I would modify the disclaimer so it doesn't contain the term "copyright holder" (as I don't want to hold any copyright). Would this be legally okay? In other words: Am I allowed to take parts of the MIT license, modify them and add them to the WTFPL license?
What other licensing possibilities do I have to guarantee complete freedom (without required attribution or anything) while making sure I'm not responsible for anything someone else does with my code (e.g. security issues that damage a companies infrastructure, etc.)?
Edit: Okay, obviously people don't like random new license texts. However, I would really like to know what alternatives exist that suite my needs.
