When a credentialed engineer puts their signature to the statement that a particular design is sound, the engineer is liable. Not the company. The engineer. If that bridge collapses, the engineer can be sued. And if the company cannot find an engineer who is willing to sign, that bridge cannot be built.
This is very important. Before we instituted this system, the USA had an average of one bridge collapse per week. And it wasn't nearly as large a country as it is today.
As long as I do not have this kind of liability, and likewise lack the power to tell a company that they are not allowed to release a website with the defects that I can identify, I do not consider myself an engineer. I may be forced to accept that my job title says "engineer", but I am firmly of the opinion that I am not one, and anyone who thinks that I am is uninformed on what it means.
