Judging from pictures, I wouldn't say that Glacialord is a knock off, rather a unique product that someone's made which happens to be compatible with a nearly 30 year old Transformer design. This isn't too different from IBM compatible computers (and components) or generic brand automotive parts (e.g. an oil filter that is compatible with a Toyota Corolla engine that isn't manufactured by Toyota).

I personally have no issue with such toys. They're not my thing, but I don't object to them at all. Heck, Hasbro's been known to make their toys cross-compatible with toys from other companies; e.g.:
* G2 Gobots (CR/RiD Spychangers) -- they're compatible with Mattel's Hot Wheels launchers and tracks. This isn't explicitly mentioned or marketed anywhere on the toy packaging, but the toys are all the same width as standard Hot Wheels cars, and their free-spinning axle gimmick allows them to conserve momentum and be launched and "fly" along any Hot Wheels sets.
* Those Movieverse non-transformable cars and track sets. Same concept as G2 Go-Bots, only worse cos they can't even transform (although they do come w/ sets so you don't have to go and buy Mattel's).
* Built-to-Rule and Kre-Os, which are of course, compatible with Lego.

I don't mind other companies making their own transforming robot toys, so long as they're distinctively original and not blatantly ripping off Hasbro's IP.

tinyJazz: I don't know if you're already aware of this, but the sales of an unlicensed fan comic was what killed BotCon Japan in 2000. The comic book was "Transformers Chronicles" by Ichikawa Hirofumi. Takara ordered Ichikawa to stop selling the books, but he was allowed to give them away for free. But this meant that Ichikawa made a substantial personal financial loss; he was initially selling the comics to break even, not to make a profit. The Japanese fan community lashed out against Takara because of this, and Takara had to work hard to repair strained relations with the fans; which culminated in Takara hiring Ichikawa to work for them in an official capacity (e.g. eHobby exclusive G1 profiles, Binaltech art and stories etc.).
