Any action YOU take as a result of being threatened with a lawsuit can be used against you in a court of law:

The judge ruled in the defamation action brought against me that because I changed my website back to its original state when threatened with a lawsuit, along with correspondence between attorneys, that my actions constituted an agreement/contract. The Pennsylvania Superior Court's opinion.

I sent the Nevyases attorney a letter of intent right after receiving the cease and desist request, and abided by the letter I sent.

Based on my experience, if you are threatened with lawsuit, I would suggest you speak to an attorney prior to considering any changes.
