You are forgetting something, which is that if the code is hosted on a social site, e.g. GitHub, many additional rules apply.

Gross misrepresentation of one's software will earn complaints to GitHub. It is the responsibility of the author that the repo's readme does not ovepromise and underdeliver.

With the caveat that author is a role, not a person. The same person may have further responsibilities in other roles. In particular, if you distribute the software directly to consumers, consumer protection laws may override some license terms.
