All technology platforms have a responsibility, but I would also say that email and SMS messages carry a large chunk of scams as well. The reality, certainly from what I have seen over my career over the last 10 years, is that bad guys will adopt whatever is being used. If Meta is the most popular platform, that's where they're going to go, absolutely. If WhatsApp becomes the dominant communication platform, I fully believe that will become the number one platform they use.
I don't think it's any one company's responsibility. I do genuinely believe we can all play a leadership role in increasing the resiliency across society.
