This is not legal advice, but I think one should always add a license, not so much for copyrights but for the "no warranty" part. If someone claims copyright once can add whatever license was used in the original work.

In general where I live (Spain), main baseline is fault/negligence, so basically "whoever causes damage by fault or negligence must repair it". They'd need to be able to attribute the fault/negligence to me, which since this is just public code with me promising nothing, will be really hard for them to "prove".

The license implicitly defaults to "I own all the rights", so no one is able to override that implicit license by copying the code and slapping their own license on top, I'm not sure if this is what you were thinking about when you said "claims copyright once can add whatever"?

Then on a different note, I'm not licensing/selling/providing any terms, so it's short of impossible for someone to credibly claim I warranted anything, there are no terms in the first place, except any implicit ones.

Maybe in the US works differently, and because Microsoft is in the US, that can somehow matter for me. But I'm not too worried about it :)

Thanks for the consideration and care though, that's always appreciated! :)
