If instead of desktop win32 applications they had used web applications none of this would have happened.

Servers are much less vulnerable for a number of reasons:

1) People managing and configuring them are more security conscious than the vast majority people. Come on, nobody downloads an email attachment or connects an USB they found in the parking lot to a server.

2) It's much cheaper to keep a server updated than a thousand Windows clients.

3) Like whitefish pointed out, even in the worst case scenario you can restore a backup and keep on truckin'.
