I think for it to be FDA-permitted, it has to have an audible or visual warning as the soft-start happens, and it has to be a certain duration. ("An audible tone or bell and/or visual warning (such as a flashing light) is recommended as", "Such warning devices are to be activated upon system start-up and are to") Even then, it is not legal for you to sell them, unless you actually register yourself with the FDA. I might be able to help you with a 555 circuit, give me a few hours and I could put together a prototype. You can look up "555 monostable" examples, but this adds complication and cost....
For FDA certification you need or should have AT LEAST:
Aperture Cap
Visible or audible warning
Delayed start-up
Labels
Safety Key?

You're very unlucky to get that kind of attention, I have very little doubt that if the hostname and phone number match, it is unlikely to be a fake. Spoofing both of those constitutes some considerable IT knowledge, but is possible for people with access to considerable resources (A large company prepared to use underhand techniques to increase or rescue sales)
