USB serial port products have beeen on the market for more than 15 years. So has USB (analog) modems. CDC ACM class emulates a modem connected to a serial port. Not quite the same as a (virtual) serial port. Anyway; the correct statement is that there traditionally was no native support in Windows for CDC ACM. Granted, there was a rather buggy serial device implementation. Forcing most manufacturers to use prorietary device classes. And CDC WMC to be developed for mobile phones. WMC allows ACM (modem), ECM (Ethernet) and Obex plus a myriad of other interfaces to co-exist in the same device. With the move to 'all-IP' CDC NCM was developed replacing ECM. Now MBIM (which builds on NCM) is native in Windows 8. And standard FTDI drivers are in-box.

'Soul Searching'

Tongue-in-cheek comment: if 'soul searching' is an important component of the response cycle to security discoveries, then suddenly I understand the difficulty that companies like Apple and Sony have had in responding to significant security issues. Both companies, after all, may be missing critical requisites to conduct 'soul searching'.
