I don't think you can really call them a knockoff. As far as I know, the HackRF has been designed as an opensource hardware[0], so I'd guess the designer intended it to be built by different entities.

There's a listing right now for just the hackrf one board at $125USD (versus a legit one at $350USD).
Hate to say it but I ordered one from there (with a metal case, high stability clock, assortment of antennas and other useful stuff) for $160.
I've had my eye on one for years, but it's just never going to be something I'm willing to drop $350+ on as part of the hobby.
