The name bfgminer was originally coined by Kano as an alternative to cgminer (he happily goes to great pains to present IRC logs proving it), and eventually adopted by lukeJr and allegedly was named after saint barbara, disguising the fact it was named after the big fucking gun.
Forks of my code I don't have a problem with. There are now dozens of them used by various asic manufacturers who feel they want total ownership of the code that is running on their hardware, and I actively encouraged people to fork the GPU and scrypt code in cgminer after I announced I was dropping support for it, including help some people set up repositories to work from.
The coloured history and association with cgminer stems from luke contributing some code to cgminer, and then forking cgminer 9 months after I started the project - as bfgminer - and then claiming through some absurd logic that cgminer was the fork because of his contributions to cgminer to that date. Since then he has continued to take thousands of patches from cgminer while cgminer has taken virtually no code from bfgminer in that time. Even if you rename bfgminer, if he continues to pull cgminer code, and continue to claim that cgminer is the clone, the controversy will follow you forever.
Controversy in the bitcoin world repeatedly follows luke wherever he goes and if he remains the main contributor and maintainer, it really doesn't matter what you name the software, the controversy will follow you.
Your problem is the association with luke-jr, not the bfgminer name.
Open source means everyone to use the code but to return back the changes that have done.
