I mean, the Adobe website flashed me pop-ups about not being in the right location, about cookies - I would choose GIMP based on this.

I choose FOSS 90% of the time because they are not beholden to the same conventions that compel most for-profit products. A lot of the concerns I'm reading about readability, marketability, etc ring absolutely true for life-or-death for-profit ventures, but there are definitely people who don't mind missing all of that stuff in exchange for good and decent software.

The goal, after all, is to be image editing software, not an advertisement.
