I, too, have a general caution about protecting privacy.  However, I am 
quite happy if the transactions with Wolfram Research's paclet server is 
providing them information about what documentation I am requesting. 
After all, it may suggest improvements that need to be made in the 

Perhaps if I were doing proprietary work I might feel differently.

The Preferences dialog allows you to uncheck automatic checks for 
documentation updates and automatic checks for data updates, so it looks 
like the option is there to maintain even this sort of privacy.
