To clarify your underlying principles here:
Are you broadly suggesting there should be rules for what type of articles can be written on the internet (presumably that align with your values)?
Are you suggesting that EFF should not have written this article (because of the $/time cost?)? And that it's okay if someone else wrote the article?
Are you suggesting that EFF should not have done the investigation in the first place, because of the $/time cost?
As an EFF supporter myself, I enjoyed the article. I liked the walkthrough of the investigation, and all the steps they used to deduce the source of the tracker. It was interesting on its face, and also educates on a methodology for making deductions for other things.
