"imagine if your data was local" misses the point hilariously badly. As though your name and email is private, and white pages phone books never existed.

"Your data" isn't your contact details. It's the record of your interactions with all the external services which by definition they get when you interact with them. Your name is...really the most worthless part of it. Facebook doesn't care and can't monetize your name, but they very much care and do monetize what you browsed and searched, how long you spent looking at it, when you did it and who you talked to.

I agree when talking about Facebook and other ad-tech companies. But "my data" is also my runs that I track with Garmin, my notes in Notion, my meals on MyFitnessPal, my events on Google Calendar...

I want to have _that_ data locally. And why are all these companies making it so incredibly difficult for me to get it? It's MY data after all!

But the default approach of every app is:

> We'll manage your data for you, in our cloud! Ah, btw, you'll only have access to it when online, and only for as long as you pay the subscription fee. Also, if we go out of business, sorry, it's gone.

> <fineprint> You _can_ request a copy of it (damn GDPR), but only once every 30 days, it'll take us 48 hours to prepare it, and we'll send (some of) it to you as a badly-formatted CSV carefully crafted to make it as useless as possible. </fineprint>
