It's also so fucking unoriginal... "hmm we need a parent company that owns all the other companies, what should we call it?" I'm not sure how the structure is, if Facebook, Instagram, WhatsApp and Oculus are separate companies owned by the holding company also named "Facebook". Obviously the websites/apps will keep their names, just a design will change, e.g. if you load Instagram, the splash screen says currently "Instagram, from Facebook", and it'll be "... from Meta" soon enough.
