Well that article clearly says "it's hurting the environment, and in my experience the vast majority of that data is useless".

Which I believe is not uninteresting, given the amount of answers here where people say "Is that data useless? I don't know, I could imagine that it's not, I think it's a hard problem". Well here we have one person saying "I have experience in that, and I can tell you that most of it is useless". Just a data point, but that's still interesting.
