Nobody but IB matters. They own the software; they develop the software. Any defect or un-upgradabilty is their fault, their problem and their job to solve. And it can be solved (not saying it might not be hard, but it can be done; it's programming, not rebuilding a used grenade).

I just hope they do it before they lose their market position. All companies, especially IT companies, will die if they don't innovate, and FT won't be an exception.
