The irony isn’t lost on me, but it does not mean the article is wrong in some way because it is published by Buzzfeed News.
If anything, I would be inclined to trust Buzzfeed’s expertise in garnering views, clicks and ad revenue from Facebook when it comes to them criticizing the system they thrive in.
Additionally, if those changes drive less traffic to Buzzfeed, it will likely hurt publishers across the board and they will all have to change to survive. Perhaps that could be in the general best interest.
