I really don't understand the defense of MS in this case. There are probably millions of small businesses that use .mdb files very regularly, and having to upgrade to another OS, another DB system, is going to be a major pain for them. For some it's going to be something they literally won't be able to afford to do when considering the extra expense of learning/retraining.

Not fixing these vulnerabilities that affect such a large number of its customers is MS's way of forcing its customers to upgrade. Rather than leaving the upgrade decision up to the customer, whose decision it rightly is, MS will leave them vulnerable to all kinds of malware in hopes they will spend more money.

Oh, I know lots of people will say that's MS's "right", but MS also has a moral responsibility to its customers too. Its customers have made it fantastically wealthy. MS owes its customers more respect than it is giving them due to that very fact....
