I think people see the word "row" is being interpreted as a horizontal line of content on a feed page because they don't know the computing definition of "data record"

And yeah, when you give a company license to do whatever they want with your data, “whatever they want” includes AI.

I think an important point is that with the decline of Pinterest's popularity, most of their data was probably acquired many years before genAI became mainstream. (Like I think I only used it around 2008-2010.) So most users probably never imagined their data could be used for training like this in the future.

In data analytics you sometimes see some weird datasets spanning across a whole lot of columns with what would be otherwise normalised in different records with relations instead.

Shit can be weird in data…
