There's a huge irony that Google, who has spent millions of dollars investing in net neutrality supporting organizations and astroturfing 'grassroots' efforts to allegedly protect the open web is blocking users from a website based on the device accessing it for anticompetitive business reasons.
Google Fiber did a similar thing: they initially banned home servers, which was later relaxed a bit to only ban commercial home servers, but regardless it shows Google's hypocrisy regarding neutrality. (Sure they had some rationalization that since they were prohibiting something entirely it wasn't really interfering with net neutrality.)
As a particular hilarity, Google Fiber has repeatedly dodged being classified as a telecom so that it isn't subject to the regulations Comcast and Verizon are.
