"Maria Markstedter – a noted author, assembly language expert, and security researcher who's written extensively about Arm at the websites she operates – received a cease-and-desist demand from Arm's lawyers. Her offense? According to the letter she shared on Xitter, using the trademark "Arm" in the domain name arm-assembly.com that she used to promote a book she wrote about the ISA."
