I mean there is of course a way to fight and win that battle and it is regulation, write things like interoperability and data portability into law and enforce it. I was more thinking of things that can be done without enforcement in the initial comment.
>write things like interoperability and data portability into law
This would be nice for sure, but I think the solution could be even simpler than that. The only successful way these centalized service platforms have managed to monetize is by gross privacy violations in support of pervasive advertising. Strong privacy laws would essentially outlaw their business models and leave a hole that a network of decentralized hobbyist services would fill.
