Rahmat Wibowo accused Alvin Prayuda Juniarta Dwiyantoro, a Google Cloud developer relations engineer speaking at DevFest Jakarta 2026, of being 'strongly suspected' of having his registration for the event cancelled, called him a 'coward' for blocking him on LinkedIn and asked 'on the way to a somasi??', tagging GDG Jakarta and Google; the email Rahmat showed says only that the organiser cancelled his registration.
