Google Featured Snippets Are Impacted By Algorithmic Updates

Dr. Pete, Pete Meyers, from Moz, posted on Twitter "Any algo update that impacts query interpretation or relevance will impact Featured Snippets." This was retweeted by Google's John Mueller, so I guess that is a vote of confidence without passing DA ;-). In all seriousness, we've all seen it, featured snippets are very finicky and change a lot but algorithm updates can cause them as well.
