Obviously IANAL, but I entirely don't see how the WTFPL (which does not ask the consumer to accept any restrictions) would create an implied contract (which would seem to be a necessary precondition for a warranty obligation)?
> The MMWA requires conspicuous disclosure of warranty terms (e.g., designations like "Full" or "Limited" as prominent titles).
> The common practice of ALL-CAPS WARRANTY DISCLAIMERS (e.g., "AS IS, NO WARRANTY") stems primarily from state adoptions of UCC § 2-316, which requires disclaimers of implied warranties to be "conspicuous" (and suggests all-caps as one way, especially in plain text).

That said, maybe it wouldn't be too hard to argue there is obviously no implied warranty with a crass license like WTFPL.
Additionally, a public-domain/CC0 license can run up against some organizations policies. It is better to release under several licenses to reach as many users as possible. Personally prefer Apache 2.0, as 10 years from now someones situation may need that...
Sad a grief'er decided to bury your response. Happy holidays =3
