I don't know what passes for law in Harold's neck of the woods, but here, he doesn't have a frickin' leg to stand on. While I cetainly can't use the trademarked name "Amithlon", assuming he actually is the legit owner of such a registered trademark, as the name for a competing product. I actually could register it for an entirely non-conflicting product; for example, if I wanted to introduce a dog food or a little blue pill called Amithlon, I'm good to go,
Then there's fair use that extends to the product (or assumed product) name. An editorial comment such as this, for example, is fully covered in the USA under the First Amendment, and all subsequent copyright laws. This is precisely why Microsoft, of late, has done an end run around the consitution by including a clause in their licensing agreement that forbids public discussion, review, etc. of their product. That doesn't make it a trademark infringement, it makes it a license infringement. If I don't license the product, I can talk about it, as long as I'm not libeling them, of course.
Then there's satire. If I decided to make a nasty, saterical web site about Amithlon, little Harold, or H&P, or anything else I like, that is fully protected and fully within my right, as long as the satrical nature of the web site is clear. This is of course why all of those sites mocking Windows, stand, today.
He's blowing hot air, plain and simple. Now, he's also free to do that, just as we are. However, I don't take kindly to assholes like him blowing hot up my ass. You shouldn't either. This guy needs to be shut down. Yet another loser trying to kill of the last few embers of Amiga interest on the planet.
You pal,
