Gary Illyes of Google was asked about sticky footers, if Google has an issue with them. Gary responded on Twitter saying "nah, I wouldn't worry about that." Meaning, Google doesn't necessarily penalize or demote sites that deploy sticky footers.
Gary did add "but do try to make them as less obtrusive as possible." "You really don't want to annoy your users," he added.
Here is the tweet:

These are currently okay with Google.
