The point is that calling the computer storage less is what’s wrong.

I can see two issues here:

Yes, that’s exactly the point. Combining data is something that must be considered. (And in some jurisdictions like the EU you even need to consider if it could be combined in future with other data)

Not sure I agree entirely. The actions I take are definitely data about me.

Also, in many jurisdictions data that could be combined (even in the future) with other data to identify you or something about you, is considered personal data.

For example, Device ID is AstridWipenaugh’s device and they use the app in the morning.

I think you’ve missed the point. It’s not the data they are collecting but the fact they say they don’t collect data.

This story has been popping up every few months for about the last decade. Usually prompted by someone with something to promote (a dumb phone, a book about downtime, some course )

I’m not sure why you’ve been downvoted. You are completely correct. There is a trail of partially finished projects. Pixelfed itself is in beta after years and years (and competitors seizing the opportunity with more polished products) , there’s SUP, Loops and that fedi directory to name three more.
