Some repos like Cromite, Ceno browser does not show any contributors on their main page despite a huge list of even recent contributors found at the insight>contributors graph.

Whereas, I've seen other repos that proudly display their top contributors (Searxng, IronFox etc). Why is this so? Do the owners toggle off a button that should show off the people contributing to the project
