If wikipedia were run on ads- that is, pageviews- then deleting a popular page because of a lack of 'notability' would result in a revenue loss, and so would be less likely that leaving it up. It's harder to hijack a for-profit to optimize for status than to hijack a non-profit, but still possible for both.

However, it is not obvious to me that wikipedia would have had the contributor growth it did if it were a for-profit project.
