This is bad advice. If you have a really good idea and a company in the same space with the money and resources to beat you to market sees it, it's very possible they will bring it to market before you.

Large companies like Google and Facebook will regularly feign interest in someone's app or idea (that they might want to purchase), only to roll it out themselves.

99.9% of entrepreneurs are never going to actually compete against Google, Facebook, et al. And if they do, it's actually not that hard because the entrepreneur's approach will be completely different.

That's the whole point of the advice: stop worrying about being copied. It's a fake problem.
