It hasn't proved to be the case for disability. It may be that there are many different kinds of disabilities, so one adjustment or one accommodation doesn't fit all.
I'd like to look at a situation slightly outside of telecom. When you use your bank card at an automatic teller, people who are blind regularly ask the person beside them for help and give them their pin number and ask if they'll help them do their banking, because the banking industry just simply has not come across yet. That's the same for phones, and it's the same in the telecommunications industry. Mobile phones, as I said earlier, until extremely recently in Canada had not started to respond at all, and we've deregulated them. So it does not respond.
