Ondřej PokornýThe Data Transfer Project (https://datatransferproject.dev/) is definitely a progress in positive direction. Especially after open standards were kinda forgotten in public discourse for about 2 decades. But it's worth reminding that data portability is only a precursor to data interoperability or, better yet, federation. Ideally, the data would be completely decoupled from the services using them as e.g. https://solid.mit.edu/ aims to achieve.
But honestly, this is up to us users to seek such change, big tech companies will hardly ever initiate it.
