The most concerning part here isn't the data itself, it's that their default data export is explicitly designed to mislead users into believing they are collecting less data than they actually do. They are explicitly and willingly breaching the GDPR here.

Can you expand on that some? What about the format is misleading? Is it because they are providing the data in separate files?

Maybe it's because by default, you get like 6 JSON files with almost nothing even when they store 250MB worth of data you only get after many emails and complaining and a month of waiting.
