Actually the EU's GDPR comes close to this with its requirements for data portability between websites. In particular, it states: "In exercising his or her right to data portability pursuant to paragraph 1, the data subject shall have the right to have the personal data transmitted directly from one controller to another, where technically feasible." [1] Conceivably this could be interpreted by EU regulators as requiring Facebook to automatically send all your Facebook posts (on an ongoing basis) to friends on other social networks (or at least to a shadow account that you've registered on some other network, which is then connected to friends in the Fediverse). If the reverse flow of data were similarly mandated (especially based on anti-trust considerations), then your friends on Facebook would be able to see what you posted on your Fediverse page. The hard part would be demanding that Facebook make your friends' posts visible in your account on another network, since that requires portability of someone else's data. There are apparently efforts being made by Facebook and other big companies to enable certain forms of data portability [2], but I worry that these are designed to distract regulators and frame the problem in a way that is compatible with the business models of the major providers.
