Sounds like you are basing your business on riding on the brand names and trademarks of others, and yet you seem to be complaining that one of your targets are fighting back?
Did you really expect anything else to happen?
According to normal trade-mark law as far as far I know it, not only do they have the right to fight back, but they also have the obligation to do so. If they do not fight back and protect their names, the resulting trademark dilution could cause them to lose the rights to the brand/trademark.
Ref. for example the case of Bayer losing the rights to the trademark "Aspirin" because they did not protect it adequately from dilution.
