But there's plenty of outright deceit. Many (most?) memecoins are some form of pump & dump. It doesn't really matter whether the code is openly public if the winners are chosen ahead of time by pre-allocating tokens.

Edit: Also actual gambling meets your criteria here. While the source code of slot machines is not public, it is typically audited to ensure it offers the odds that are advertised.
