That's an interesting counterpoint, to a common conversation here.
I suppose it's important to realise that even if a public domain declaration isn't possible in Germany etc., that doesn't mean the Unlicense is unusable. Unlicense, as you know, explicitly grants certainly permissions; it doesn't simply say "this is public domain".
There was another interesting point in the thread you linked. Even if Public Domain isn't possible, courts will tend to consider the clear intent, whilst reading the legal text in a way compatible with local law. https://lists.opensource.org/pipermail/license-review_lists.... So maybe you cannot waive certain moral attribution rights, but the intention is clearly to allow use, copying, and modification, without payment to the author. Worst case, that's an MIT style license.
