Yes, a fair point that was mentioned in the article.

I may be speaking only for myself, but I don’t want any new features enabled by default. Subsequent popups and warnings may be hastily ignored/skipped during a user’s busy day, so it’s too easy to accidentally give consent, and consent shouldn’t be accidental.

Let users know about the feature in a newsletter or “what’s new” section of the site, and let the user opt-in to try this new feature (if they wish). That’s really the only ethical, transparent, and 100% way to ensure consent.
