It seems likely that most of the user base of Windows 7 Pro is in that category. It's the version you get as a power user or small business, when you need more flexibility and control than the Home version offers but you aren't big enough for Enterprise and all that comes with it. So even the average user of Windows 7 Pro probably is technically competent and probably does have good reasons for using that version. Obviously Microsoft can choose to shaft those people anyway. After all, what are they going to do, sue? However, in doing so, it's going to further alienate a substantial and influential part of its user base. There are going to be consequences for that in the long term, or possibly even the not-so-long term if they start bundling essential security updates with other potentially undesirable things very soon as part of this exercise.
