This is hardly a good example to all the aspiring startup folks on how to treat your users.
Perhaps the old guard/high karma users keep posting here in part because they know they have a large audience. What makes you think they would stick around if the site were walled off?
Edit: Removed the accusation of trolling, apologies for that.
This is about what the community wants and needs. pg and the other long-term users want the community to stay a certain way, hence this item itself; closing off that community to only those that participated in the development thereof will allow the community to remain where it is desired.

The same thing that made them stick around when the site did not have a large audience.
