You're incorrect, and underestimating the potential profit vs cost. 5c per outbound call, but even if the scammers get 1 or two people a day for $100 (and likely MUCH more), it's just a drop in the bucket to operating costs.
I doubt I'm incorrect. There were 46 billion robocalls in 2020. That would be a $2.3 billion operating cost. Make it 10 cents and its 4.6 billion. Robocallers are not making 2-5 billion per year scamming people.
I wonder what’s the ballpark of what spammers are making and spending. And if that really is significant enough profit to the carriers to prompt inaction on an issue that clearly degrades the experience for the rest of their users.
Or maybe this issue couldn’t be solved unilaterally, where one carrier could offer much better spam protection as a competitive advantage, and the industry is too decrepit for group effort that doesn’t have direct implications on their bottom line.
