I would say it mostly only applies to famous people and events that lots of people can keep going like whack-a-mole if one source is nuked, or that they can maintain easily as a small part of a large information database (like wikipedia). If you’re a virtual no-name, nobody as random individuals are going to be paying attention to maintain your footprint and, well… in the capitalist context, companies are not going to want to foot the bill to maintain it.
