Aggressive, sure, but also seems:
a. reasonable for AI ethics experts to "lead" in issues surrounding AI ethics
b. not the cardinal sin of discussion that it appears to be viewed as here.
You'll see people here defending Linus or Elon Musk for saying objectively way worse stuff than this.
Somehow Timnit is defined by this discussion, but Elon isn't defined by calling a rescue diver a pedophile with no evidence or Linus telling someone to kill themselves.
