So far Spez's legacy includes, in no particular order:

Changing other peoples' comments
Starting a war with the 3rd party app devs who made reddit the easily accessible platform it is (browsing reddit on the toilet wasn't nearly as common before the first apps came out, and all of the first ones were 3rd party)
Being a moderator on the jailbait subreddit, a community for sharing sexually suggestive pictures of underage teenage girls
Forcing new moderation teams on communities whose moderation he didn't agree with
Straight up lying about the 3rd party apps and their developers every step of the way

Way to go, Steve Huffman! You had a community of volunteers build your platform for you and now you're taking it all away from them. I'm sure this won't backfire.
