I mean this percentage-wise, vs the technology etc.

but can companies just flee to another juristiction where this law doesn't apply?

so there should be some law that graduate the ownership

ofc. small startups shouldn't be owned by users right away

but at least it's possible to reverse engineer this - e.g. for compatibility with Libreoffice/Openoffice

though one can argue that the text-file format lock-in makes users valueable

it's primarily a tool for individuals

e.g.: Microsoft Word doesn't gain its primary value from users

how is this different from other types of technology?

including everything the "fediverse" does today

and let users own their own data, so they can move it if they want

so maybe the law should be: open up the platform
