Not sure and IANAL but the GDPR text is a bit weird on that. Article 9 has section e) which says that information 'manifestly made public' relating to 'special categories' is excluded. What's weird is there seems to be no such exclusion for personal information which does not relate to special categories. Having this 'opt-in' certainly seems to tick the box for consent. However, if reproducing information from a publicly available bio would fall foul of GDPR requirements, then I think there are bigger fish to fry than a hobby project made by a guy who at least seems to trying to respect people's preferences.
