Who would bear that cost though? My prediction would be the customers again, because they would make the phone support harder to reach than it already is as a "solution" to the increased demand for phone support.
Partially yes, longer support waits. But there's a threshold where the agents either need to be available or the reviews / opinions about a telco go too low, so it can't be just ignored.
I just don't have sympathy though - ideally people would DoS all the telco and local government lines until the issue is fixed. It's just stupid how many years this exists without obvious solutions.
