I think that the laser focus on the use of the word "lazy" isn't really warranted considering the author isn't a native English speaker. His use of "lazy" meant more along the lines of "taking the easy way out". It was a reference to the WebKit team giving a list of several APIs that they were not going to implement because of privacy concerns. It takes little to no effort for the WebKit team to simply throw their hands up, yell "Privacy concerns!", and then refuse to implement or engage in a discussion on how to improve the APIs. That's why the term "lazy" was used, and while I would have phrased it differently, I think it's abundantly clear that the author wasn't calling a person or persons lazy, merely describing their actions as the easy way out.
