At some point, this question became community wiki but I don't see a compelling reason for it to remain so.
Just a note, there are quite a few deleted answers on that question which I'm assuming helped push it to CW status.
I think that manually removing CW status from questions may be a slippery slope later.
CW status is automatically put in place to minimize people piling answers on high-view questions in the hopes of getting easy reputation. If we manually remove the CW status on questions, then it circumvents that mechanism, which I think is a good mechanism. We do regularly get answers on older questions, and that will increase as we continue to grow.
If we want to remove that mechanism (or change the threshold), it will make the current issue with hot questions even more pronounced in the short-term, so I'm not a fan of that idea.
Again, for this question I don't see it as much of an issue now, but I think we may want to use caution going forward in making this sort of request. At least by having this comment here, anyone who stumbles across this request in the future will realize that it should be viewed in the context of when and why it was done, rather than carte blanche to ask CW status to be removed.
Removing the automated community wiki status is something we should approach with the understanding that once a moderator removes the community wiki, the system will no longer step in and apply this safeguard, should additional answers pile on.
On such questions, it's our responsibility as a community to ensure we watch such posts to keep them free of spam, me too, and low quality answers.
The question is already protected against answers from very new users, so this shouldn't actively harm our site and should be fine. But let's all be sure to keep our eyes open for trouble, if it gets bumped to the top of the active page again.
I've removed Community Wiki status from the question. It was auto-CWed because it crossed the answer threshold, not including deleted answers (15 non-deleted + 4 deleted = 19 total; threshold is 15).
