I do not think he is the only one. I, as a consumer, do not care either. Was the copied amp patented? If not, then welcome to America. Capitalism at it's finest. Copying is just another form of flattering. Not to mention that it tends to lead to further development as people try different things. Maybe a better way to look at this is how the original amp builder/designer has contributed to the hobby as a whole. I seem to remember Steve Jobs making this same complaint to Bill Gates. Where did it get him?
I think the reason you were banned was not what you were saying, but how you were saying it. Frankly, almost all of your post there were abrasive and condescending. I seem to remember somebody that knows you better than I telling you so. I personally would have at least given you a few days off and asked you to use more tact in your replies. If that didn't work, then you would be banned. You need to remember that the things you type do not always come across the way you might have wanted it. Everyone will read it from their perspective.
Shouldn't this bitterness really be directed at x-force then?
Are you involved with their marketing? Are you just upset that someone else might be doing a better job of promoting themselves? Once again, as a consumer, why should I care if one design is similar to another? I'm sure the first person to build an internal combustion engine felt the same way when Henry Ford started cranking out Model T's.
I am not trying to be an a$$. However, it seems like you are just bitter about being banned.
