I think the issue they want you to be aware of is that when opening/closing a fiberglass hood it can cause stress marks or damage the hood. The factory hood struts are supposed to hold up a much heavier steel hood and then you throw a fiberglass hood on and it can cause to much stress to those points. I really havn't seen any other aftermarket hoods that DO NOT use factory hood struts.

Of the different types of hoods were built, some have the factory steel hood frame for strength, some pure fiberglass. I got mine used and I am pretty sure its a early pfyc hood but people have said its this and that also... I know I can carry it by myself with little effort so I think its pure fiberglass and so far I don't see any noticable stress marks using stock hood struts.
