Being secure is the lack of attack surface. So it's really hard to say. Often what hits you is something you haven't considered.

So what the author is saying he doesn't take responsibility for when you use the result of his work and get problems. If you want to act responsibly build a team of different experts, have tests for security scenarios, have automated tests, from time to time pay people to attack your system and show the weaknesses you have.

Or, do it like 99.9% of people and just accept that there are risks but don't try to put resulting failures on people who provide free solutions for you online.

PS: Incorporation is a good way to protect yourself. Then having even ineffective due diligence processes is enough to protect your personal life from the risks of doing business.
