Responding late, but yeah, you raise a valid point. The difference to me is in the purpose of the two facilities. A toilet is there for the employees' physical needs and more or less no other purpose. A computer is there primarily to do business work on. The company has a clear need to be involved in how that computer is used in several ways, such as maintaining its security, monitoring its performance, making sure it isn't misused, etc. They can afford you some privacy, but only on a best-effort basis because it's not reasonable to be entirely hands off.
