Your Unpopular Decision Isn't Done When You Announce It
You made the call, posted it in Slack, and got two thumbs-up from the people who argued against it. Three weeks later the work is slower than before. Disagree and commit, as most leaders run it, leaves the people who lost the argument alone with the cost. Buy-in after an unpopular decision gets built after the announcement, and part of that work belongs to you.
