I agree with you in general. However, as others have already pointed out, Facebook wants to claim protection for a really (REALLY) wide range of goods/services.

I agree with you in general. However, as others have already pointed out, Facebook wants to claim protection for a really (REALLY) wide range of goods/services. If granted, pretty much anyone selling software or hardware using "book" in its name might be vulnerable to bullying by Facebook's lawyers. Typically, one just registers a word trademark for a very small number of service/goods classes (e.g., here's a registered trademark for "car" which only applies to certain medical devices and services [1]). A large company trying to claim "book" for pretty much the whole Nice Class 9 is not normal behavior.
