Someone could sue you for publishing code that causes them damage, if they tried to use it in the way it can reasonably be expected to be used. And this is not such a bad thing to have to deliberately renounce. You can imply the safety of something just by giving it away for free. If you built a swingset and put it in a park, you imply that it's safe to use. If a child injures themselves because it breaks, you are liable. Better to say "I don't accept any responsibility if this swing injures you", and let people infer how confident they should be in using it. That's fair, because trust is a reasonable thing to have, and if you can't express the confidence in your product that justifies the trust people have in it by default, they should be made aware of that explicitly.
