Benchmark, one Silicon Valley’s top venture capital firms, is suing Uber’s founder and former CEO, Travis Kalanick, claiming fraud and other transgressions.

As evidenced by the recent spate of stories, Kalanick was grossly irresponsible and tended towards cutthroat business tactics. My belief is that what goes around comes around. Kalanick acted unethically, and now he’s paying the price.

I always tell startup founders not to cross the line. It’s good to be aggressive. It’s good to push the limits. But don’t do anything illegal or unethical. That’s crossing the line.
