It has become for many an essential service.
Facebook ( in many countries ) is a monopoly, unassailable competitively due to the size of its network.
In days of yore, such a huge monopoly that is a utility would be broken up like Ma Bell in the 1980s or like rail, water and electricity in the UK were nationalised.
Consumer data protections are currently woefully insufficient.
I propose that such vast walled gardens should be curtailed for the public good.
Thus Facebook should be just as viewable without signup, data exportable and deletable in whole or in part.
Facebook should provide an API so competing and extending services can be freely built on it, restoring competition and innovation and niche utilities it brings.
Consumers should be free to use whatever services and programs they choose on their own data whether stored on Facebooks servers or downloaded and held privately.
Huge transnational data monopolies should not be walled gardens.
