Because twitter users care more about the convince twitter provides than they do about the risks their privacy and security as a result of using twitter. I suspect most have no idea what the risks are or have some very limited idea of some of them. Maybe if they had a better understanding of the risks they'd close their accounts and move to something new, but I doubt there be enough of them to cause twitter to invest in securing the unnecessary amounts of data they collect. This sort of thing will only be fixed when we hold companies accountable for failing to protect customer data through regulation with many rows of sharp teeth.
