People don't like discussing money - their mortgage amounts - how much they borrowed - how much they earn. In fairness the articles don't make much sense unless you have this information.
Then you also have the fact that people don't like discussing financial hardship.
Finally, those in financial hardship are normally the ones trying to eke out an existence. It's called having a heavy 'mental load'. When you have this mental load, dealing with the bank/giving interviews to the press is the last thing on your mind. It's simply a case of trying to get from one day to the next.
On a personal note. I believe that the length of time it has taken to sort this, plus the low level of appeals to date, is directly related to this mental load. The banks are counting on it. People get their tracker back and redress. They are relieved not to have to carry around this mental load anymore and don't take their appeals any further. It's how come there isn't so much uproar.
