I always enjoy some indication of each individual's own ethics/morals in the conversation along with some discussions of practicality. However, the laws of the land(s) are reasonably clear. Perhaps they differ between some posters' jurisdictions and/or the IP is not protected in all relevant jurisdictions. I'd personally start there. However, if one's own interpretation of what's "right" or "should be allowable" is more important, then enjoy yet another rehash of the topic.
If the seller of this item posted something akin to below for an F6 replica, I'm sure some people may still buy it... but would any of you? That's rhetorical, I really don't want to know.

I have made for sale to you an interpretation of a First Watt F6. It does not use some of the same highly sought after parts as an authentic F6. I have no idea if its audio performance is similar to an authentic F6. I've simply reposted some specifications of an original F6. The F6 you buy from me may not perform this way at all. I've seen other people that have built amps like this one call it an F6, and it's based upon the circuit of the F6, so I am sure it's close enough.
An authentic First Watt F6 was sold by General Amplifier and/or affiliates through authorized sources. They are no longer in production, and they were made in limited runs. The primary creator of these products, Nelson Pass, has released the schematics of the F6 for Do It Yourself use. I've chosen to turn this into a business opportunity because I assume you, my potential buyer, either can't or simply won't Do It Yourself and build one. I'll also assume that you either do not have or simply do not want to spend the money to get a real one. Note that this circuit design, the First Watt name and logo, and the name Pass Labs, may still be protected by copyright(s), trademark(s), and/or patent(s). Heck, the boards I use may even be protected. I've chosen to use all those things in order to lure you to my sales page. However, it may be illegal for me to sell this product to you, and it may even be illegal for you to possess it in your jurisdiction. I don't know, and I have not bothered to check. Lots of people on internet forums think that it's okay, and I've gotten away with it before. What I do know is that lawyers are expensive, and it's unlikely that either of us will suffer any consequences. Enjoy your amp!
BTW - I hope you'll also check out my Neurochrome stuff. I'm not sure where I sit on this legally either, but it's AWESOME!

That's tongue-in-cheek. Maybe it's all legit. Different cultures have different personal boundaries around "knock offs" for commercial sale. As stated, I haven't bothered to look up all the relevant info re: a stance on legal grounds. I'll give the seller the benefit of the doubt until proven otherwise, but I admit to wondering if something's afoot at the Circle K.
