Claiming that you worked at company X when you didn't is like claiming that you have a degree from a university that you didn't attend, and is one of the most clear-cut and common examples of professional deceit. I don't think this is a sexism issue at all -- look at how roundly Alexey Vayner was mocked. While I don't think the TechCrunch article was an example of charitable judgment, people are bloodthirsty and love to string up an "example case" every so often.
