In some third-world countries you cannot get a telecom licence unless you "implement" this, or your license could be easily revoked or canceled.

In Russia, for example, there are explicit regulations which says that no telecom company can operate unless it provides "monitoring and law-enforcement facilities".

My guess is that each country nowadays has regulations of this sort, so telecom equipment manufactures are forced to "add required functionality". Of course, US has such "secret" regulations.)

So, it is much better to face the reality and to standardize this shit to reduce the pain of telecom "workers".)
