I generally agree with what Bob (first poster) and Elizabeth stated as reasons. Generally, moderators will remove a thread if they come to the conclusion that maintaining the thread via constant moderating activity (reviewing flagged posts for deletion and removing such posts if warranted) is more work than removing the thread. Moderators are patient, to a point.
Manufacturers having contributed to a thread don’t have any bearing on the actions of the moderators, unless the manufacturers play a direct role in the moderator’s decision to remove the thread (for example, posting inappropriate content posts that trigger flagged posts for review).
