Censorship is the suppression of speech or deletion of communicative material which may be considered objectionable, harmful or sensitive
Quality control would be removing spam, nonsensical content or, in some cases, content that's wildly off-topic.
Considering the original T-Shirt Hell story was run here without being "quality controlled" away, it seems reasonable to accept that a followup is, therefore, not off-topic for HN. That makes the removal of said story censorship and not quality control.
