Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

I'm not mad at speedmaster. Anybody that doesn't realize that EVERYTHING they sell is a chinese ripoff/copy of sumbody else's stuff is an idiot.
I have bought stuff from speedmaster, at their black friday sale, because the price savings is SOOO good, i cant resist.... because if i had to buy from a u.s. manufacturer, i would pass on the puchase, cause the price would be three to five times as much money.
Do I know it's a copy... sure.
Do I expect first quality stuff....no.
Do I have parts i wouldn't otherwise have?...... you betcha!
